[mpich-discuss] Segmentation fault (core dumped) on windows 7 32-bit with cygwin

[Addison Rich]

Any insight?  I'm thinking it might have something to do with either the
weird error about fortran compilers, or that I was trying to install 64-bit
version of MPICH2 on my 32-bit machine.  How do I make sure I am building
and installing the 32-bit version? Can't seem to find any documentation on
this.

Thanks.
