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

[Addison Rich]

Hello,

I've successfully built MPICH2 after disabling the fortran options during
config (make was complaining about syntax errors in some header files,
which stopped after I got rid of fortran), but I cannot run any programs
(such as the basic hello world, or cpi that comes in /examples/ without
getting this segmentation fault error.

Here's an example of the mpiexec.hydra.exe stack trace:

Exception: STATUS_ACCESS_VIOLATION at eip=00423B0F
eax=00000000 ebx=00000000 ecx=00000000 edx=611883A0 esi=00227698

ebp=00227668 esp=00227650
program=C:\mpich2-1.4.1p1-install\bin\mpiexec.hydra.exe, pid 6056, thread
main
cs=001B ds=0023 es=0023 fs=003B gs=0000 ss=0023

And attached is a run of mpiexec with -verbose.

Thanks, and any insight would be appreciated.
