nhc98 error messages
What does this error message mean?
Like all compilers, the error messages produced by the nhc98 are
sometimes difficult to understand. Here are a few tips as to what might
have gone wrong.
Only 32 words after gc, need 32 words
The garbage collector failed to reclaim enough space - the program is
out of heap. Try re-running with +RTS -Hn -RTS where
n is a bigger heap size, e.g. 16M.
Type error: cannot unify types Prelude.2 and Prelude.3 at 133:9
In type errors, pairs, triples, and other tuples are denoted by their
arity - thus Prelude.2 means pair. The notation 133:9 means line 133,
character position 9.
arityIS in IntState.hs couldn't find 376
If you get an error message like this and you have an (n+k)
pattern in your program, then you have found a bug in the compiler.
Please report it!
