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the product is no longer active in Red Hat Bugzilla.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.
Previously, G++ would crash on an invalid code in the gnu++11 mode when using an initializer list with invalid value in its constructor. This has been fixed in such a way that the constructor is better checked for an erroneous values.

Source code. Title is VTTest.C
Description of problem:
If a programmer mismatches angle brackets while using initializer lists to create a C++ vector<vector<T> > object, g++ can seg-fault instead of throwing a syntax error. An example is shown in the attached short piece of code.
Apologies if this has been fixed already. I'm new to this site and had trouble accessing the "frequently reported bugs" list; our web browser here at work is several years out of date.
Version-Release number of selected component (if applicable):
gcc version 4.4.7-3
How reproducible:
Everything needed to reproduce this should be in the attached text.
Steps to Reproduce:
Compile the attached text with "g++ -std=gnu++0x -c VTTest.C".
Actual results:
Segmentation fault.
Expected results:
Syntax error.
Additional info:
While I was tracking down this bug, I came across an (apparently unrelated) second issue. I suspect the second issue is probably an error on my part rather than a bug. However, I decided to mention it anyways. It is described briefly as a "sidenote" in the definition of the Tag class in the attached text.
