Trying to find the cause of one or more errors, might involve libopal.so

Built openmpi-1.1a1r9351 on Debian Linux on Operton with PGI 6.1-3 using "./configure --with-gnu-ld F77=pgf77 FFLAGS=-fastsse FC=pgf90 FCFLAGS=-fastsse"

My program generates the following error which I do not understand:

Signal:11 info.si_errno:0(Success) si_code:1(SEGV_MAPERR)
Failing at addr:0x4
[0] func:/usr/local/lib/libopal.so.0 [0x2a959927dd]
*** End of error message ***

Is it possible I'm over running the OpenMPI buffers, my test program works fine other than the "GPR data corruption" errors (uses MPI_SPAWN and posted previously); the basic MPI difference between my test program and the real program is massive amount of data being distributed via BCAST and SEND/RECV.
