Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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

Description Adam Seering 2013-03-14 20:38:48 UTC

This is a request to pull in a bugfix from upstream.  The upstream bug is:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56403
Further detail is specified at the upstream bug report.

Description of problem:
When I compile an example program (code included in the upstream report), I get an internal gcc error:

"""
internal compiler error: in build_zero_init_1, at cp/init.c:279
"""

Along with a request to report the bug.


Version-Release number of selected component (if applicable):
RHEL 6.*
(Various versions of gcc from 4.2 through 4.7 are known to be affected.  See the upstream bug report.  gcc 4.4.5 on RHEL 6 has specifically been tested.)


How reproducible:
Always


Steps to Reproduce:
1. Attempt to compile the example code file included in the upstream bug report

  
Actual results:
gcc emits an internal error


Expected results:
gcc compiles the program.  (Or, alternatively but less preferably, gcc indicates that there's a code syntax error or some other input problem.)


Additional info:
This bug has been fixed upstream.  Details and discussion on the bug report in question.  The fix has been backported through gcc 4.6 already.  The fix appears to be a very simple one-line change.

Comment 2 Adam Seering 2013-04-17 19:01:30 UTC
