Funny, I've been meaning to write in on this.
I hit this problem hard too. I was linking the GHC compiler to a C
library. I compiled the whole compiler with -prof, but whenever it
called into the C library it would core dump. For a long time
(years!) I assumed it was something strange my C li
Hi Uwe,
I'm sorry about the delay replying to this message. I've investigated
your problem and its another of those "Hmmm, why doesn't this break

Hi,
I'm using ghc-4.08.1 on linux (Debian 2.2) and running some nofib
tests. some of the tests (e.g. mkhprog) fail when comparing the
expected / actual stderr.
The two files differ by an extra carriage return on the actual
stderr's saved file.
I discovered that this was caused by the line 23
Hi,
Parsing rules seeems to be a little broken. Two examples:
1. The following program compiles fine under 4.08, but fails with a
nearly up to date CVS head:
module Main where
{-# RULES
"silly" forall arg .id arg = arg
#-}
main = putStrLn "Hello World"
with error:
@zip:ha
But those instances may be used by a module which imports this one. I
think Sergey's comment is correct.

You may be interested in Mercury ("a purely declarative
logic/functional language) which has such a binding to Mercury called
MCORBA. Mercury can be found via

and a paper describing the implementation can be found via

Hi Volker,
It is legal Haskell, but it isn't doing what you think. The patterns
in a case statement introduce *new* variables, their scope is the
right hand side expression of their alternative.
Since the a,b,c patterns are just variables they will match anything,
and the first alternative w
Thanks for the bug report. I am investigating. In the meantime you
could change the declaration of ArgrC from a 'newtype' to an ordinary
'data' declaration. It then compiles fine for me.
Hope this helps

If you look on the GHC download page for version 2.10 you will see
that there is a patch for the Makefile there. I think this is your
problem.
It would be great if you can get version 4 running on Alpha, but I
suspect that your problems are only just beginning ;-)

Hmmm, just a me-too :-(
it dies very quickly, just after a couple of calls to times according
to strace and possibly in a function called Main_main_info() according
to gdb.

FWIW, I built it with libc5, hacking hsc with an editor wasn't very
appealing! Giuliano's bug report seems to be still outstanding, and
there's been no new release of glibc2.1 since.

Hi,
What's the latest on this problem? Since I've hit it too :-( Is it
possible to build ghc with egcs and glibc2.1 ?? I'm trying to build
from source using the pre-built ghc-4.02 linux binaries.

Hi,
I wish to use the FiniteMap module, lib/exts/FiniteMap.lhs, but want
to use it from both GHC and hugs. As it is hugs can't use it because
it imports PrelBase. (btw, why didn't it make it into the joint
GHC/Hugs Libraries? - seems v. useful).
As far as I can see this can be fixed by pla

Hi,
I'm sending this to g-h-bugs because there is certainly a ghc bug,
however any answer may also be interesting to readers of g-h-user so
consider cc-ing them if appropriate.

As you can see I stole the parser from an example. It parses boolean
expressions.
