Hi Quincy, I'll be pulling pieces out of the large c++ project into a small test c program to see if the seg fault can be duplicated in a wieldable example and if accomplished, will send it to you. MemoryScape and gdb(Netbeans) doesn't show any memory issues from our library code and hdf5.

Hi Quincey, [got the 'e' this time] The problem cannot be repeated in a c example program because the problem is upstream use of vector's with a -= operation. The failure in this area did not show except in this mpi application even though the same library and code is used in single
