skia2/tests/PathOpsBuilderTest.cpp
caryclark 580c40ae71 link test to bug
crbug.com/526025 includes a minimized SVG test case.
Translating that test case into native code (fuzzTNG)
did not reproduce the bug. That test case should
have not been included with skia issue 1323813003,
and is deleted here.

Running the minimal test case in a modified version
of chrome isolated the bug. The modified version
generated the test fuzz763_3 with the edit

#define DEBUGGING_PATHOPS_FROM_HOST 1

in src/pathops/SkPathopsOp.cpp line 188.

Rename fuzz763_3 to issue_526025 to associate the test
with the bug. Note that the bug contains the body of the
CL in comment $5.
