It's long been a Fortran optimization to stack-allocate arrays (from the days of all-the-world's-a-VAX when loads of code broke that assumed SAVE attributes). It's an FAQ here for the intel compiler and well-optimized gfortran, and there are other good reasons for large stacks compared with the 10MB-ish default.
