I've installed Wolfgang Thaller's ghc 6.4 dmg on my G3 iBook running
MacOSX 10.3.8.
ghci works fine, but attempting any compilation fails with the message:

Hmmm... you might have stumbled upon two different bugs;
1) GHCi crashes with object files that have no dynamic symbol table -
should happen only with toy modules

Yes, I can confirm that.
I don't understand the message on the last line. Is GHC confusing GH

It looks like GHCi just tries to load all files passed on the command
line that do not have a known extension as an object file.

After a day of running gdb in parallel on my MacOS X and Linux [quite

The entry code for BCOs expects all parameters to be on the stack, but

instead of panicking.

The following causes a Context reduction stack overflow:

that was just about undecidable
If a callback into Haskell code finishes very quickly, a deadlock
occurs. Adding a small delay helps.
This is what I think happens:
rts_evalIO creates a haskell thread
rts_evalIO calls scheduleExtThread to spawn a new OS thread. When the
callback is finished, schedule() calls
to lack of disk space.
Any Ideas?
