Sometimes the easiest way to track down non-specific errors like
"memory fault" in Fortran programs is to compile with array
bounds checking turned on. That's the "-C" option to f77. It's amazing
how many programs just stomp all over their storage. (I've seen cases
where this is deliberate, but most often it's an error.)
