Description of problem
openmpi fails to build if "-Werror=format-security" flag is used.
btl_usnic_module.c:829:5: error: format not a string literal and no format arguments [-Werror=format-security]
We are working on a proposal to enable "-Werror=format-security" for all
packages. Once this flag is enabled, GCC will refuse to compile code that could
be vulnerable to a string format security flaw. For more details, please see

How to fix this
The fix for these errors is quite simple. It's a matter of changing a
Please fix this issue in rawhide with a patch (which you should submit

there should be no harm in pushing out this fix/patch with other needed

In the event you don't fix this bug before the next mass rebuild,
provenpackagers may step in and update your package(s) to fix this
Build openmpi-1.7.3-1.fc21.src.rpm with "-Werror=format-security" flag to reproduce the problem.

Fixed and reported upstream.
FWIW: This has already been fixed in the OMPI 1.7 branch and will be included in the 1.7.4 release.
The code actually moved to a different .c file -- if you care, here's the new fixed location:
