--- Comment #15 from Bernd Schmidt <bernds at gcc dot gnu.org> 2010-11-25 16:05:36 UTC --- Can you go back to the failing sources and test whether http://gcc.gnu.org/ml/gcc-patches/2010-10/msg02569.html fixes the problem? For future bug reports, please use gcc -v -save-temps, then post the preprocessed source and the exact options that were passed to cc1. I've managed to reproduce the code generation, but only with an explicit "-march=i686" which required some guessing.
