RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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

The actual alias is
alias delenv 'eval `delenv.pl \!*`'

Comment 2 RHEL Program Management 2011-01-07 15:37:29 UTC
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
representative.

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.
