With the expression: words (repeat 'a')
Using WinHugs Sep 06 I get a stack overflow.
Using Hugs Linux May 06 I get a GC fails to reclaim sufficient space error
Using GHC and Yhc both of these succeed.
I have a similar issue in one of my functions which is showing the
same behaviour.
assuming you've got a terminating application in mind,-) a slightly
more interesting expression is:
test span = span (/=' ') $ replicate 100000 'a' ++ [' ']
without optimizations, hugs is prone to fail for such deep applications
of non-tail-recursive functions like span/break, splitAt, ..
try this variation:
span p l = span' p l id
where
span' p [] = \c->c ([],[])
span' p xs@(x:xs')
| p x = span' p xs' . (\c (a,b)->c (x:a,b))
| otherwise = \c->c ([],xs)
