I am running an application which creates animated gif images from different set of image frames in a loop. This application uses set of transparent gif frames, opaque gif frames, png image frames, jpg etc in the given order. Exactly during the third iteration, the VM crashes. That is, when creating the gif image from set of PNG image frames.

This is reproducible consistantly across WinXP and Solaris10-JDS with Mustang-b43.

I have attached a sample test. Untar it and run the sample test. It will automatically pick-up image files from different folders available in the same directory and tries to create the animated gif. Click 'Next' button repeatedly. You would notice a VM crash during the third iteration.

Here is the crash info:
