[compiz] Crash in blur.c (SIGSEGV)

[Artur Uszyński]

Hello.

System info:
OS: FC6 x86_64
video: Nvidia GF 7900 GT, driver version 97.55
compiz version: git
config backend used: ccp

I can reproduce this crash every time on my system. When blur plugin is active and I try to access any right-click menu, regular application menu or drop-down list, compiz crashes. Backtrace produced by crashhandler plugin shows crash in blur.c in function blurWindowResizeNotify, in the following line:

        if (bw->state[BLUR_STATE_CLIENT].threshold ||

The values of bw seem to be wrong and IMO indicate classic problem with null or uninitialized pointer (although I'm not a programmer):

        bw = (BlurWindow *) 0x0

Sometimes instead of 0x0 I get values like 0x40 or 0x33373b3338393932, which don't seem to be right either.

After restarting compiz and immediately accessing exactly the same object (for example repeating right-click on desktop) crash does not happen, but then accessing other similar object crashes compiz again.

After commenting out the whole "if" statement mentioned above compiz no longer crashes, but probably graphics glitches are introduced instead.

There was a report including similar description sent on Wed Feb 21 04:34:20 PST 2007:

"changing the filter type" might be a symptom of the same problem (accessing drop-down list).

Here is exemplary backtrace:
