I suspect the problem is related to sizes of basic data types.  On a pure
32bit box you probably won't get the differing modes.  Thus the bug does
not exhibit itself.

I suspect if you build a cross compiler for mips-sgi-irix6  that you'll
be able to trigger the problem using the "-mabi=64" switch.
