If you hit a crash in 2.6.3_rc1 or later, I want to know about it, but anything before that will just result in me asking "does it happen on 2.6.3?" ... ;)
Actually I am experiencing a crash in 2.6.3_rc1 that I did not have before. I built a window manager (e16) against the libs and headers of 2.6.3_rc1, and X11.bin was crashing whenever I exit the window manager. Normally, I exit the window manager and X11.bin quits cleanly. I reverted to 2.6.2 and rebuilt the same code, and no crash.
