Bad eta expand during building

2005-03-16 Thread Axel Simon
Hi,

I'm just trying to compile ghc 6.4. I was a bit put off by ton's of Bad
eta expand messages scrolling off my screen. It looks like this:

Bad eta expand

__coerce GHCziBase.Z0T{(w) tc 40}
(CmmParse.zgzg{v rej3}

   (__coerce CmmParse.Env{tc r3CI} eta{v sb4W}))

stage2/utils/FiniteMap.hi

I don't know which files this refers to as there were way too many of
these messages to scroll back. But the next file is obviously
FiniteMap.lhs

Does this message have to scare me? And if yes, why does the build
proceed?

Axel.

don't worry abou thtem.  I keep meaning to look into it again, but it's
harmless I think. Certainly long standing
