[MPICH] Problem to run MPICH2 codes under Win64

[Hu, Peng]

Hi all,

I am having trouble to run my parallel MPICH2 executables under Win64
environment(EM64T). My parallel executable file is complied by intel 
fortran 9.1. Every time I ran my code, I got error like the following:


------------------------------------------------------------------------

forrtl: severe (157): Program Exception - access violation

This happened even for singleton processor which only calls MPI_init and
do not do any real parallel works. 

I already set up windows firewall correctly to allow my file to run.
There is also no trouble for C codes under Win64. Under Win32, it also
went
through without any trouble.   


Does anyone have any idea about it? Is this a intel fortran bug, MPICH2
bug or something else?


Thanks a lot!
