Package: xserver-xfree86
Version: 4.3.0-7
Hi,
xserver version 4.3.0-7 (testing distribution) crashes, when launched
on a kernel with exec-shield (by Ingo Molnar) patch applied. Always can
reproduce that. Previos version of X server from testing (4.2.1) didn't
have any problem with exec-shield. Here's output:
lexa:/home/lex# cat /proc/sys/kernel/exec-shield

lexa:/home/lex# X
