GDB crashes while parsing Xorg coredump
Last modified: 2012-07-15 04:42:14 EDT
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):
Steps to Reproduce:
1. gdb /usr/bin/Xorg /tmp/core.X.#####

coredump bt when answering 'y'
Created attachment 597782 [details]
coredump when answering 'n'
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
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.
