take (-1) [] fails
As described in the Haskell report, Prelude.take
applied to a negative argument and an empty list should
return an empty list. Hugs and HBC implements this
correctly, but GHC's implementation instead produces
Exception: Prelude.take: negative index
I have two large programs, that work fine when compiled
with HBC, and fail because of this when compiled when
GHC. I have examined all direct calls to take in one of
them and I am 93.7% certain that they cannot be the
cause of the problem, so I suspect the offending call
to take comes from another prelude/library function...
