I believe this is a caught SIGTRAP signal (negative exit code usually
means it was an unhandled signal).

According to the signal man page this is
       SIGTRAP        5        Core    Trace/breakpoint trap

I don't believe this is coming from mvapich but from your application.
Can you get a backtrace from the core file that should have been
generated?

Also please note that mvapich-1.2 is old and unsupported.  I strongly
suggest that you update to the latest stable mvapich2 (1.8.1) or try our
latest release (1.9a2).
