The added test case contains the binary JSON equivalent of
["ž"]
with the modification that the string's length has been set to INT_MAX. In
Value::usedStorage this length is used through the pointer d like so
s = sizeof(int) + sizeof(ushort) * qFromLittleEndian(*(int *)d);
Because 2 * INT_MAX is UINT_MAX-1, the expression as a whole evaluates to 2,
which is considered a valid storage size. However, when converting this binary
JSON into ordinary JSON we will attempt to construct a QString of length
INT_MAX.
Fixed by using String::isValid instead of Value::usedStorage. This method
already takes care to avoid the overflow problem. Additionally, I've tried in
this patch to clarify the behavior of Value::isValid a bit by writing it in a
style that is hopefully more amenable to structural induction.
Finally, the test case added in my previous patch had the wrong file extension
and is renamed in this one.

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.
Linux X11:
* The user must be logged in to an active desktop; you can't run the
autotests without a valid DISPLAY that allows X11 connections.
* The tests are run against a KDE3 or KDE4 desktop.
* Window manager uses "click to focus", and not "focus follows mouse". Many
tests move the mouse cursor around and expect this to not affect focus
and activation.
* Disable "click to activate", i.e., when a window is opened, the window
manager should automatically activate it (give it input focus) and not
wait for the user to click the window.
