Summary: GHC's stack blows up

Initial Comment:
When compiling the included file (part of AFrob)
with GHC 5.04 under Linux, GHC's stack blows up. I've
tried to increase the size up to 20 Mbyte (at which
point compilation takes a loooong time, and then the
stack still blows up), and I've tried all four possible
combinations of -O and -fglasgow-exts. The result is
the same in all cases.

I used variations of the following command:

ghc -c -package lang -package posix -package concurrent
-i/usr/local/lib/ghc/imports/hgl:/usr/local/lib/ghc/imports/arrow:/usr/local/lib/ghc/imports/afrp:../Common
+RTS -K20M -RTS -o RSParser.o RSParser.hs

The result I got in all cases was:

stack overflow: use +RTS -K<size> to increase it

Everything worked fine with GHC 5.02.2: no need for
+RTS -K<size> or anything.

If you need more context, try the AFRP/AFrob
Hacker's pre-release available from
www.haskell.org/afrp.

All the best,

/Henrik

I managed to compile this with the forthcoming 5.04.1, so I 
suspect it was another instance of the newtype bug that was 
causing the compiler to go into an infinite loop.
