Doesn't help.  I didn't expect it to -- my code shouldn't be divving by zero,
and anyway the bus error happens *immediately* on startup, whereas it wouldn't
call floatRat for half a minute if it were working.

The first code I posted was my shorter attempt.  At any rate, it's hard to
pull stuff out of this and still have it work.  And I've had versions which
did compile with profiling when the version before or after wouldn't.  This
one doesn't, on my Sun.  Does on the Linux box...
