[mpich-discuss] Code crashes when compiling with GFORTRAN but not when compiling with PGF90

[Rajeev Thakur]

It's strange. We test with gfortran regularly. Just again make sure you have
compiled and built correctly with gfortran, i.e., both F77 and F90 are set
to gfortran before running configure. Then run make clean and make.
