*** Bug 673239 has been marked as a duplicate of this bug. *** I am not sure what you are showing here? If you mean #c2, then it is a distilled testcase for a gcc bug for which I've just posted a patch for review, see http://gcc.gnu.org/ml/gcc-patches/2011-01/msg02059.html Should be fixed in gcc-4.6.0-0.5.fc15, now just glibc needs to be rebuilt. Seems fixed with glibc-2.13.90-2.x86_64. Closing. |
