Comment 3 RHEL Program Management 2011-05-31 14:10:34 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.
Comment 8 Kamil Dudka 2011-09-09 12:45:21 UTC 
I got the crash above with 32bit libcurl in mock.  With the patched version of libcurl, it does not happen any more.  On x86_64, I was not successful in reproducing the crash with any version.
