Yes, but:
\begin{code}
module Main( main ) where
main = putStr $ show q
where q = quot 1 (0::Int)
\end{code}
gives: Fail: Prelude.Integral.quot{Int}: divide by 0
IIRC, Integer isn't Div-By-Zero-checked (for performance reasons).
But my core dumps, don't give any "blahblah exception (core dumped)"
messages. The programs just die (at a very early stage). I still think, it's
something with glibc stuff...
Cheers,
