Iain,
    The ELF style weak ref issue appears to be red herring. I find that both
darwin10 with Xcode 4.2 (whose build of libitm has a config.h with
HAVE_ELF_STYLE_WEAKREF undefined) and darwin11/12 with Xcode 4.5.2 (which
results in config.h having HAVE_ELF_STYLE_WEAKREF defined) exhibit this
regression. In both cases, removing the trailing linkage on -lcrttme.o
eliminates the segfaults in the test case.
     Is there some way to modify darwin.h's SPEC handling so that the linkage
on -lcrttme.o  isn't passed for the g++ compiler? As I understand this, we are
only linking in crttme.o to provide stub symbols when libstdc++ linkage isn't
present to provide those symbols.
