Description of problem: My current coredumps generated by Xorg xorg-x11-server-1.12.2-3.fc18 are leading to coredump (see Bug 839565) A problem internal to GDB has been detected, further debugging may prove unreliable. Quit this debugging session? (y or n) It basically doesn't matter when I answer y/n - in both cases coredump happens - though logs seems to be different. I've no idea whether debuginfo for Xorg is broken. Version-Release number of selected component (if applicable): gdb-7.4.50.20120703-12.fc18.x86_64 How reproducible: Steps to Reproduce: 1. gdb /usr/bin/Xorg /tmp/core.X.##### 2. 3. Actual results: Expected results: Additional info:

The Xorg core file really is not available?
No in both cases the core file for Xorg and approriate debuginfo packages were present on my system. After downgrade to these packages: $ rpm -qa | grep xorg-x11-server 392196 xorg-x11-server-utils-7.5-12.fc18.x86_64 1612042 xorg-x11-server-Xnest-1.12.2-3.fc18.x86_64 3373920 xorg-x11-server-Xorg-1.12.2-3.fc18.x86_64 134431 xorg-x11-server-common-1.12.2-3.fc18.x86_64 1400045 xorg-x11-server-devel-1.12.2-3.fc18.x86_64 1807361 xorg-x11-server-Xvfb-1.12.2-3.fc18.x86_64 74015846 xorg-x11-server-debuginfo-1.12.2-3.fc18.x86_64 I'm able to get the core dump from crashing Xorg without any problems. However newer version of Xorg packages seems to confuse gdb. I'm not really sure where is the fault - possible wrong debuginfo package for Xorg, however gdb should not probably generate coredump in this case anyway.

I believe invalid DWARF is either in /home/kabi/soft/glx-test/lib/xorg/modules/drivers/intel_drv.so or in: /home/kabi/soft/glx-test/lib/libdrm_intel.so.1 Please attach these, thanks.
/home/kabi/soft/glx-test/lib/xorg/modules/drivers/intel_drv.so is the Comment 6 attachment.
