OS X framework + ghci linker + RTS flags = bus error?

The dynamic linker appears to interact in a strange way with RTS
command-line flags on OS X. (version 10.2.8, with ghc-6.2.2;
although ghc-6.2.1 and ghc-6.3.20041009 also seem to have this
problem).  Here's a simple example:

******************************
// BusErr.m

#include <Foundation/Foundation.h>

int foo(int n) {
    NSLog(@"In foo.");
    return n;
}

******************************

>gcc -c BusErr.m
>ghci -framework Foundation +RTS -RTS BusErr.o

Loading package base ... linking ... done.
Loading object (static) BusErr.o ... done
Loading object (framework) Foundation ... done
final link ... Bus error

******************************

A similar error occurs when using foreign code from a framework
in a Template Haskell splice  (which is where this matters to me).  The 
error is avoided either by using ghc instead of ghci, by removing the
"+RTS -RTS" flags, or by removing the call to NSLog (or, eg, replacing 
it with printf which is not linked via a framework). 

I've tracked the bus error to the call to NSLookupAndBindSymbol in
rts/Linker.c (on the symbol "_NSLog", in this case) but can't
figure out anything more than that.  

Thanks in advance,
