--- Comment #3 from Ben Woodard <woodard at redhat dot com> ---
I've been looking at the data from the latest run and we actually have two
incidents of this and both of them were created with the XLC 12.1 compiler.
Therefore I think that it is rather unlikely that it is just a corrupted
binary. Rather I think it is more likely a bug in the XLC 12.1 compiler.

When the data is corrupt, if we can just exit gracefully that would be fine.
