[mpich-discuss] I have a question

[Anthony Chan]

It appears your fortran code has an illegal access of memory.
Since you are using intel fortran compiler and assuming you have access
to the source code, recompile the code with -traceback (and probably -g)
which will display a backtrace of where segfault occurs.
