Description Vojtech Vitek 2010-11-26 11:38:42 UTC

+++ This bug was initially created as a clone of Bug #650363 +++

Description of problem:
I have an alias
delenv eval `delenv.pl !*`

When I call
delenv PYTHONPATH /shows/cis/sw/lib/python/common /shows/cis/sw/lib/python/`/bin/uname -i`
tcsh will core dump

When when I call
delenv PYTHONPATH /shows/cis/sw/lib/python/common /shows/cis/sw/lib/pytho/x86_64
tcsh does not core dump.

I seems to be tied to the backtick evaluation on an alias that also has backtick evaluation.

Version-Release number of selected component (if applicable):
6.14-17.el5_5.2

Comment 3 Vojtech Vitek 2011-04-19 12:02:40 UTC

This bug was present in tcsh 6.14 (RHEL-5.6) but was fixed in tcsh 6.17 (RHEL-6.0) by reimplementation of string functions in sh.glob.c.

Closing as WORKSFORME.
