You are using MPICH on a workstation network, where the underlying
message-delivery system is currently p4.  Your program (in particular,
process 1) has a bug in it causing it to give a segmentation fault.
p4 is intercepting the interrupt so that it can kill off your other
processes on the network and not leave them dangling.

If you suspect problems in MPICH itself, please send a bug report to
mpi-bugs@mcs.anl.gov.
