Hi,

The following (obviously not valid) piece of code 

> data A = B {
>   f :: Maybe (w :: Int)
> }

causes Hugs (both 970330 and 970410) to fail with a message
  
  INTERNAL ERROR: depTypeExp

I traced the source of this message to a function named, surprise,
depTypeExp in src/static.c.  

Expected behavior would be, I guess, an error message less suggestive of 
compiler bug.
