We have just made a set of simple MPI-programs to test MPI-libraries for 
openib, because we encountered problems when we used BLACS/SCALAPACK. 
One of these test programs was a memory leak test. If look at bug report 
#970 it is still open.

For openmpi i did the same tests (NO optimization -O0 -g) for 
SCALAPACK/BLACS/BLAS and with gcc version 4.1.1 some scalapack test just 
hang just like with MVAPICH2
