J2DBasher reliability is crashing after 2-3 hours on Windows-XP with B77 2D PIT build. On b76, it was crashing after 15-20 hours on Linux/WinXP and the issue was identified to be the same one addressed by 6295525. The stack trace of the crash was different on Mustang-b76. This bug got fixed in b77 PIT build and we tried running the tests on the PIT build. Now it crashes after 2-3 hours and the stack trace is different from the previous one. 

Since the reliability suite is too huge, I am not able to attach it and I have given the location under 'Comments'.

This crash is reproducible only after we updated the Reliability testsuite for Mustang, including the GIF Writer and animated GIF scenarios. Before that, it was running fine for 120 hours. It is important to note that the reliability tests overwrites the same set of output files what was created in the first loop, for every subsequent run. 

Here is the crash info:
