[Scalapack] Probable Bug

Hello,

I've got a OSX Intel Cluster with LAM-7.1.3  running on it and using  
gfortran 4.3.
In the 32-bit mode all is well...
However in the 64bit mode I get an error while running two of the  
test routines for PBLAS.

One of the processes started by mpirun has exited with a nonzero exit
code.  This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.

PID 11576 failed on node n0 (132.250.147.1) due to signal 4.
