#5293: Linker error from integer-gmp (OS X 10.7)

Architecture: x86_64 (amd64) | Failure: GHC doesn't work at all
-------------------------------+--------------------------------------------
I recently upgraded to the latest dev build of OS X Lion and Xcode 4.2,
and I've been
having some linking issues related to `integer-gmp`. I installed
`ghc-7.0.4-x86_64` from
the .pkg with no apparent problems, but running `ghc --make test.hs`
(where test.hs is
simply `main = print "Hello, World!"` (attached, for convenience))
produces the following:
{{{
Linking test ...
ld: warning: could not create compact unwind for _ffi_call_unix64: does
not use RBP or
RSP based frame
ld: illegal text reloc to ___gmp_modlimb_invert_table from
/Library/Frameworks/GHC.framework/Versions/7.0.4-x86_64/usr/lib/ghc-
7.0.4/integer-gmp-0.2.0.3/libHSinteger-gmp-0.2.0.3.a(mp_minv_tab.o) in
___gmpn_modexact_1c_odd for architecture x86_64
collect2: ld returned 1 exit status
}}}
The bit about the unwind was present on my Snow Leopard install with Xcode
4.0.2, and
there were never any problems. What ''is'' new is the illegal text reloc
error. What little
I've been able to find online seems to suggest that this is due to Xcode's
linker now being
a bit safer (read pickier) and giving errors where once it might have
given warnings.
I considered building `ghc HEAD`, but of course without a working `ghc`
that's a bit of
a futile effort.
I understand that Dan Knapp (dankna) has also moved up to Lion and is
having no such
issue, so I am particularly curious about our differing experiences. It
may be that the
picky linker is only a product of the most recent dev build of Xcode, but
I can't be sure.
Any thoughts or pointers would be greatly appreciated. Also, apologies if
I've put the ticket together incorrectly.
