Hi Joerg,
This problem is almost certainly bug #751.
This gives a compiler crash if the threaded run time system
is used. The latest darwinports ghc (which I maintain) builds
the run time without threads. What is the output of
sudo port info ghc
?
If you do not have revision 2 of the 6.4.2 portfile, you need to
update:
sudo port selfupdate
`port info ghc reported that it was _not_ revision 2 and so I did
the `selfupdate' as advised. this went OK. I then did
sudo port upgrade ghc
Upgrading ghc (or any other port in darwinports) after you have had a
build crash is not reliable.
There is no way to tell darwinports this yet, so you have to manually
sudo port uninstall ghc
sudo port clean --all ghc
And try to build again with
sudo port install ghc
but this did not go so well:
after some fetching/compiling it crashed and a second try yielded:

as in the first attempted `upgrade' the problem seemed to be the
unability to fetch readline51-001 from any site.
The problem is that you can't fetch readline, so that you can't build
the required
readline dependency. First, make sure your version of OS X is fully
updated.
Apple has shipped broken version of curl, which is used by
darwinports to fetch files.
Then make sure your DP is updated (yes, it is best to run
sudo port selfupdate
yet again.)
If you still have trouble a workaround was posted to the darwinports
mailing list.
Note that if your DP installation is in /opt/local, the fetched
files are stored in
/opt/local/var/db/dport/distfiles/<port name>. You can fetch the
distribution
files manually and put them in the appropriate directory to work
around such
problems.
Best Wishes,
Greg
what is a poor guy to do? where is(are) my fault(s)? up to now I've
been 'fully elastically reflected' by ghc :-(
all the best
joerg
If you are running the latest version, your experiences
are... interesting.
Best Wishes,
Greg

hi,
my very first tries with ghc, using the 'program'
module Fact where
fact :: Integer -> Integer
fact n = product [1..n]
gave the following compiler crash under MacOS X 10.4.7 (ghc
installed from source via DarwinPorts):

Please report this as a compiler bug. See:
http://www.haskell.org/ghc/reportabug
more irritating, this error was _not_ reproducible. a second try
did run through:
`ghc -c fact.hs' yielded a file `fact.o'
but `ghc -o fact fact.o' yielded:
