Application Binary Interface, basically the assembly-level calling
semantics. If the tests run successfully, then this is not the problem.

Both examples work without crashing. Pretty weird...

One more to try: mat/examples/tests/ex16f90.F

This call works from one Fortran module, but not from another? I suspect
stack corruption, perhaps from something as simple as the wrong number of
arguments to an earlier call. (Fortran having nearly worthless type
checking.)

The non-F90 VecGetArray() and MatGetArray(). But if MatGetArrayF90() is
working when called in a different context, then this shouldn't be
necessary.
