I'm also going to try building on 10.4.x to see if this is 10.5-
specific.
One more variable is that the build on 10.5 was done on a machine
with an Intel Core 2 Duo processor. I don't know if that's relevant.

If you have installed my binary distribution you don't need to
compile
the sources anymore (except for the sake of testing).
This is purely for the sake of testing. As the subject
indicates, I'm trying to build GHC from source on 10.5. I've
built earlier versions successfully on 10.4.
I did do a "make clean" between attempts, but I will try
throwing the source directory away and re-extracting from the
tar archive next.
One possibility is that if you compiled GHC via C (I believe this
is still the default in 6.6.1), then changes in the gcc shipped
with 10.5 might be causing problems. You might get further by
adding
SRC_HC_OPTS = -O -fasm
GhcStage1HcOpts = -O -fasm
GhcStage2HcOpts = -O -fasm
GhcLibHcOpts = -O -fasm
to your mk/build.mk. This might fix your build, but you'll still
be left with some incompatibility between GHC and the gcc in
10.5. You already encountered one such problem, when using -
split-objs, right? If you get a successful build it should be
easier to debug this.
I already have a usable build -- the 6.6.1 binary release that
Christian put together works fine on 10.5.
Actually there appears to be a problem with that 6.6.1 binary
release, at least on your system. Both crashes that you described
were in the stage1 compiler, which is compiled by your installed
6.6.1. So either
(a) your installed 6.6.1 is generating bogus code (which is why I
suspected a
gcc incompatibility, because that would explain why Christian
doesn't
see the same crash)
(b) there's a bug in GHC which makes it segfault on OS X 10.5.
I'd say (b) is highly unlikely - GHC just a Haskell program (well,
mostly), and it therefore shouldn't segfault.
Still, you tried with -O -fasm and that didn't help. So I'm at a
loss to explain why your stage1 GHC is crashing. Probably the only
way forward at this point is to get out gdb and figure out what's
going wrong.
Cheers,
Simon
