Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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.

Bug 1095306

Summary:	Disable strict-aliasing optimization for rsh

Whiteboard:
Fixed In Version:		Doc Type:	Bug Fix
Doc Text:	Prior to this update, the rsh application was optimized through strict aliasing rules, even though it is not a performance-sensitive application. As a consequence, the GNU compiler collection (GCC) generated warning messages about breaking the strict-aliasing rules, despite correct functionality being the priority for rsh. With this update, strict aliasing has been disabled for rsh. Therefore, GCC now ignores the strict aliasing rules and no longer interrupts rsh processes with warning messages. However, this may also lead to a slight decrease in performance.	Story Points:	---

Comment 2 Michal Sekletar 2014-05-07 13:12:23 UTC

AFAICT, whether all this is problem or not really depends on optimizer and how clever it tries to be. rsh is not performance sensitive application so I propose to disable in RHEL7 as well.
