Description of problem: XDMCP connections to gdm x86_64 segfault. I do not know how to attach gdb to this because the instance of gdm-binary is launched with each XDMCP connection. Since it has no tty, it outputs to dmesg: gdm-binary[18655]: segfault at 0000005596fc0570 rip 0000005596fc0570 rsp 0000007fbffff1e8 error 14 I have been unable to rebuild gdm due to Bug #132903, but it seems judging by the changelog that the latest 2.6.0.5 upstream version does not solve any problem like this. Version-Release number of selected component (if applicable): gdm-2.6.0.3-5
I am having the same problem on 386 architecture with "kdm". Using strace I found that if I have a x-terminal definition in /etc/X11/Xservers than kdm crashes. If I comment this line it does not. Is this similar or not. Plus, I am not sure where the problem is because KDE 3.2.3 kdm works fine!
My problem was kdm related and has been fixed in the KDE_3_3_BRANCH.
Seems fixed in September 22nd rawhide.
