Seems like it would core dump on divide-by-0, so unless it already
printed a useable stack trace, maybe you could see approximately
where it is happening via e.g.

% gdb sander core
> where

(where core might be core.xxxx) and look at that routine in the code.
For more debug detail, if needed, try adding -g to all compile options,
'make clean', recompile, see if the error still happens (may be
suppressed by diminished optimization), and try gdb again w/ the newer core.

If you can find where it is happening, it could be a clue to the
presumed compiler failure.

It may be less hassle overall to just try g77.
