Thanks for this bug report.
I've fixed this in 4.08 (Simon: only in your source tree). It turns
out that the HEAD doesn't have the problem.

| Hi!
|
| Compiling the program
|
| >main =
| > do
| > _ <- compute "_"
| > return ()
| >
| >compute :: String -> String
| >compute ("hd"++_) = "_"
|
| with
|
| ghc -c Bug.lhs
|
| results in the obvious errors
| but compiling with
|
| ghc -O -c Bug.lhs
|
| rather results in
|
| <<loop>>
|
| which looks to me like a bug in ghc.
| I tried this with
| ghc 4.08,4.08.1 and egcs 1.1.2 on solaris and linux
|
| bye,
| Axel
