Description Bastien Nocera 2006-05-24 09:48:51 UTC

The version used to reproduce the problem on RHEL3 was tcsh-6.12-11.EL3, on i386.

+++ This bug was initially created as a clone of Bug #188279 +++

We got the segmentation fault of tcsh when executing their csh
script.  However, the csh script is not related to segmentation fault.
Using RHEL4 IA64.  Also, the architecture is not related. 

Version-Release number of selected component (if applicable):
tcsh-6.13-9

How reproducible:
Sometimes

Steps to Reproduce:
Executing a csh script

Actual results:
core dump

Expected results:
no core dump

Additional info:

The customer is using tcsh-6.13-9.ia64. The following is backtrace of
dump.
__stack_pointer is 0x0, and snum in palarm() is wrong, too.

(gdb) bt
