If it is not repeatable, it is often bad hardware.

gcc (and Mercury) use quite a bit of memory, and tend to exercise
bad memory or overheated CPUs quite a bit.  fatal signal 11 is a
very common error with bad memory.  I'm not sure what fatal signal 4
is about.

The other thing that can cause this is old versions of gcc, but I
don't think 2.7.2 is too old (haven't checked though).  If it is
an old version of gcc, it should be repeatable -- you should not
be able to keep going by running make again.
