When I compile with Electric Fence (linux Athlon XP) I get a floating point exception on startup.
The stack trace:

When I recompile with ARENA_DOD_FLAGS = 0 (include/parrot/pobj.h) I no longer get the exception.
Something funny is going on but I'm too swamped chasing an IMCC bug to do anything about it. Hopefully someone else has cycles.
