My guess is that the error is here. There's a bug in ghc where (x `div`
0) and (x `mod` 0) will results in a seg fault. For now (according to one
of the Simons, this is fixed in the next version) you should do something
like:
floatRat r lim
| den == 0 = error "division by zero"
| otherwise = num * 10 ^ lim `div` den
where num = numberator r
den = denominator r
If that doesn't fix the problem, perhaps you can try to whittle the
example down to something shorter.
