--- Comment #59 from Jack Howarth <howarth at nitro dot med.uc.edu> 2011-02-05 18:40:15 UTC --- I can confirm that the patch in Comment 58 both eliminates the failure in the reduced test case from Comment 56 as well as the failure in the dipCoup test in xplor-nih. I am less certain that we want the current phrasing of the comment... +/* FIXME: Work around PR47558 by linking against libSystem ahead of + libgcc_ext. */ We should arrive at a consensus on whether symbols which overlap between libgcc_ext and libSystem should be given priority in libSystem and resolved there. This patch achieves this and if we agree this should be the case, the comment should instead read... +/* Linking libSystem ahead of libgcc_ext prioritizes those overlapping symbols in libSystem + over those from libgcc_ext which re-exposes PR42333. */ This is the correct behavior for the long-run on darwin and we should re-double our efforts to get <rdar://problem/7457013>, ___divdc3 slightly wrong, fixed in Lion.
