Bug 37900 – sys-kernel/development-sources-2.6.1 causes xterm to segfault.

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description dynamotwain 2004-01-11 11:13:37 UTC]

I just upgraded the kernel from 2.6.0 to 2.6.1.
Now xterm segfaults in the call to XrmPermStringToQuark.

Steps to reproduce:
1. Install linux-2.6.1
2. Start an X session (prompt> X&)
3. Start xterm (prompt> export DISPLAY=:0.0; xterm)
4. XTerm crashes, says it's a segmentation fault.
5. debug it: (prompt> gdb `which xterm`)
6. Start the program (> start)
7. Look for the problem function.

Expected Results:
No segfault, and a terminal in the X display

Versions:
kernel - 2.6.1 vanilla
X - xfree-4.3.0-r3

Is this still a problem with > 2.6.1 ??

I have a 2.6.1 kernel here that I am moving on from and I cannot duplicate this (just out of interest). 

[Comment 2 dynamotwain 2004-02-08 12:44:27 UTC]

I haven't tried anything newer than 2.6.1 yet.
I'm waiting for 2.6.3 b/c of all the ALSA patches
for my soundcard.

[Comment 3 dynamotwain 2004-02-28 12:41:22 UTC]

No problems with kernel 2.6.3
