Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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

Build log on fedora-16-ppc64

Description of problem:
gambit-c up to version 4.6.3 builds cleanly on ppc64, but this is no longer the case with the latest two releases

Version-Release number of selected component (if applicable):
gambit-c-4.6.5-1.el6

How reproducible:
Always

Steps to Reproduce:
1. fedpkg clone gambit-c && cd gambit-c
2. fedpkg switch-branch el6 && fedpkg srpm
3. rpm -i gambit-c-*.src.rpm
4. rpmbuild -bb --with ppc64 gambit-c.spec
  
Actual results:
See attached log for 4.6.5 (on Fedora 16; the EPEL 6 target in mock is currently broken)

Expected results:
Build succeeds

Comment 3 Michel Lind 2012-04-02 04:16:31 UTC
This bug is fixed in GCC 4.7.0 (as tested on the PPC test machine's fedora-rawhide-ppc64 target) but present as late as GCC 4.6.2 (tested on the fedora-16-ppc64 target) as well as the GCC 4.4.6 release shipping with EPEL 6.

Compiling with -O1 (which is the default up to Gambit 4.6.3) works around this problem, but upstream points out that it's a GCC problem.
