[issue920] Incomplete backtrace in gdb

[Hasso Tepper <sinknull@xxxxxxxxxxxxxxxxxxxxxxx>]

New submission from Hasso Tepper <hasso@estpak.ee>:

With current HEAD and gdb 6.7.1 I can't get complete backtraces any more. 
Example from Xorg.core:

(gdb) bt
#0  0x283409c8 in kill () from /usr/lib/libc.so.6
#1  0x2838b04a in abort () from /usr/lib/libc.so.6
#2  0x08193de5 in FatalError ()
#3  0x080b4f15 in xf86SigHandler ()
#4  <signal handler called>
#5  0x081695e6 in XkbEnableDisableControls ()
#6  0x0816ab79 in XkbRemoveResourceClient ()
#7  0x0807b766 in ?? ()
