The xorg-server randomly crashes with segmentation fault. I usually can reproduce this bug by these steps: 1. open Chromium or Opera; 2. type smth in search edit. When the history list is dropped down - the X server crashes. This method is working every time, and X server crashes randomly for unknown reasons as well; for example: I can just seek on track in Amarok, or just look at monitor and drag mouse up and down :) The X server may or may not crach in this case, and if I produce actions described above, with Chromium or Opera, - the X server crashes always.
If I check xorg's log, I can see such lines:
Backtrace: 0: /usr/bin/X (xorg_backtrace+0x35) [0x486efd] 1: /usr/bin/X (0x400000+0x55e61) [0x455e61] 2: /lib/libpthread.so.0 (0x7fa4a5582000+0xf120) [0x7fa4a5591120] 3: /usr/bin/X (dixLookupPrivate+0xa) [0x440bf2] 4: /usr/lib64/xorg/modules/extensions/libglx.so (0x7fa4a2dcb000+0x34982) 5: /usr/lib64/xorg/modules/extensions/libglx.so (0x7fa4a2dcb000+0x2d7ed) 6: /usr/bin/X (FreeResource+0xae) [0x4431fe] 7: /usr/lib64/xorg/modules/extensions/libglx.so (0x7fa4a2dcb000+0x2b29b) 8: /usr/lib64/xorg/modules/extensions/libglx.so (0x7fa4a2dcb000+0x2d607) 9: /usr/bin/X (0x400000+0x2d4a3) [0x42d4a3] 10: /usr/bin/X (0x400000+0x24d1e) [0x424d1e] 11: /lib/libc.so.6 (__libc_start_main+0xfd) [0x7fa4a3c82bbd] 12: /usr/bin/X (0x400000+0x247f9) [0x4247f9] Segmentation fault at address 0x290 Fatal server error: Caught signal 11 (Segmentation fault).

I have Gentoo x86_64, and I build xorg-server with CFLAGS = CXXFLAGS = "-Os -march=core2 -pipe" You can see some info about my system, and logs in attached files.
