HUGS error messages

[Joerg Doelfer]

When loading a program into the Hugs Interpreter (Version 1.4) I get the
following error meassage

  ERROR "EsmCheck.hs": Instance storage space exhausted

Does anybody know how to fix this problem?
Do I have to compile a new version of Hugs with more memory for the
instance storage section?
Does anybody know if there is a list of HUGS error messages (with
comments)?
