The core of the problem is that the system is asked to lookup the metrics for a character with id == 0. This causes a hit in the fCharToGlyphHash matching the sentinel glyph. This happens because fCharToGlpyhHash is initialized with all zeros, therefore, the fID is zero matching the char with id == 0. The fAdvanceX field of the sentinel glyph is in fact not initialized.
The bigger question is now did a zero character get passed to getUnicharMetrics?
The breaking code is basically as follows:
wchar_t glyph = L'S';
paint.measureText(&glyph, 2);
This get mischaracterized as a utf8 string instead of a utf16(?) string. Because of the little endian ordering, this is the character string 'L' '\0'. Since the size of the original string is two bytes (but a single character) the '\0' is treated as its own character and past to getUnicharMetrics.
TEST:
On windows failed using DrMemory. With this change does not fail.

This path renderer converts paths to linear contours, resolves intersections via Bentley-Ottman, implements a trapezoidal decomposition a la Fournier and Montuno to produce triangles, and renders those with a single draw call. It does not currently do antialiasing, so it must be used in conjunction with multisampling.
A fair amount of the code is to handle floating point edge cases in intersections. Rather than perform exact computations (which would require arbitrary precision arithmetic), we reconnect the mesh to reflect the intersection points. For example, intersections can occur above the current vertex, and force edges to be merged into the current vertex, requiring a restart of the intersections. Splitting edges for intersections can also force them to merge with formerly-distinct edges in the same polygon, or to violate the ordering of the active edge list, or the active edge state of split edges.

The looper can generate more than one quad, but if any one is degenerate,
give up, but not before generating the state for the line join to
produce the correct end.
Before, the early return allowed the inside path to contain multiple

Also: Add SkDeflateWStream and associated unit tests.
SkPDFBitmap is a replacement for SkPDFImage. As of now, it only
supports 8888 bitmaps (the most common case).
SkPDFBitmap takes very little extra memory (aside from refing the
bitmap's pixels), and its emitObject() does not cache any data.
The SkPDFBitmap::Create function will check the canon for duplicates.
This can reduce the size of the output PDF.
Motivation: this gives another ~40% decrease in PDF memory overhead
TODO: Support other ColorTypes and scrap SkPDFImage.

There was a scaling mistake visible in some JPEG images because the ratio between Y, U and V planes were assumed to be the same ratios as the ratio between texture sizes, which was wrong because texture have a minimum size of 16 and are rounded up to the next POT. Since the ratios between Y and UV planes are generally 1, 2 or 4, rounding up to the next POT would generally preserve this ratio, so that this bug was not very visible, apart from very small jpeg images of 8 or less pixels in either width or height.

SkStream is a stateful object, so it does not make sense for it to have
multiple owners. Make SkStream inherit directly from SkNoncopyable.
Update methods which previously called SkStream::ref() (e.g.
SkImageDecoder::buildTileIndex() and SkFrontBufferedStream::Create(),
which required the existing owners to call SkStream::unref()) to take
ownership of their SkStream parameters and delete when done (including
on failure).
Switch all SkAutoTUnref<SkStream>s to SkAutoTDelete<SkStream>s. In some
cases this means heap allocating streams that were previously stack
allocated.
Respect ownership rules of SkTypeface::CreateFromStream() and
SkImageDecoder::buildTileIndex().
Update the comments for exceptional methods which do not affect the
ownership of their SkStream parameters (e.g.
SkPicture::CreateFromStream() and SkTypeface::Deserialize()) to be
explicit about ownership.
Remove test_stream_life, which tested that buildTileIndex() behaved
correctly when SkStream was a ref counted object. The test does not
make sense now that it is not.
In SkPDFStream, remove the SkMemoryStream member. Instead of using it,
create a new SkMemoryStream to pass to fDataStream (which is now an
SkAutoTDelete).
Make other pdf rasterizers behave like SkPDFDocumentToBitmap.
SkPDFDocumentToBitmap delete the SkStream, so do the same in the
following pdf rasterizers:
SkPopplerRasterizePDF
SkNativeRasterizePDF
SkNoRasterizePDF
Requires a change to Android, which currently treats SkStreams as ref
counted objects.

and a simple one (circle). We loop over all combinations of clip ops, aa/bw clip,
and inverse/non-inverse clips.
This GM triggers a current bug in the gpu clipping code which fires an assert. Thus

This CL fixes 5 bugs related to hoisting image filters:
For image filters the src layer (the one prior to filtering) often needs to be
smaller then the final layer. This requires the saveLayer's optional bounds
to be stored (in SkLayerInfo.h and SkRecordDraw.cpp) and then used in
compute_source_rect and carried around in GrCachedLayer.
The image filters can add an extra offset to the final draw operation.
This is now computed in GrLayerHoister::FilterLayer and carried around in
GrCachedLayer.
Filtered layers must use exact matches. This is now done in GrLayerCache::lock.
The filter cache requires a valid matrix so it can compute the correct offset.
This is now done in GrLayerHoister::FilterLayer.
Filtered layers need to be drawn with drawSprite while unfiltered (and therefore
hopefully atlased) layers can be drawn with drawBitmap. This is now done in
draw_replacement_bitmap.

Remove SkLCGRandom. We already decided the new one was better, which is
why we wrote the new SkRandom.
Convert GMs that were using SkLCGRandom to use the improved SkRandom.
Motivated by the fact that these GMs draw differently on some runs. We
believe this to be a result of using the old SkLCGRandom.
Add each of the tests that were using SkLCGRandom to ignore-tests.txt,
since we expect they'll draw differently using SkRandom.
Move a trimmed down version of SkLCGRandom into SkDiscretePathEffect.
In order to preserve the old behavior, trim down SkLCGRandom to only
the methods used by SkDiscretePathEffect, and hide it in
SkDiscretePathEffect's cpp file.

MULTILINE, ^, and $ work based on the platform, but the files being
parsed are from other platforms. As a result, the current code for
extracting the actual_results.json version will not find it in
logfiles produced on Windows when run on Mac.
The code for extracting the exact actual_results.json file to use
from a logfile is itself something of a hack, as this information
should be provided ina more structured manner. This proposed
method of finding the exact file is no worse than the old one, and
in cases like above, better.
