Summary:

SELinux is preventing /usr/bin/gdb "write" access on gdb.

Detailed Description:

SELinux denied access requested by gdb. It is not expected that this access is
required by gdb and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report.
