I'm going to try. In the meantime, I did other tests on this machine, which is detected by clang as -march=corei7. Compiling this with the system's clang (which has been compiled with -march=core2) and -march=core2 is OK. Compiling this with the system's clang (which has been compiled with -march=core2) and -march=native is OK. Compiling this with the bootstrap clang (which has been compiled with -march=native) and -march=native FAILS. The problem seems to be inside the clang compiled with -march=native. Next, I'm going to try with a bootstrap clang compiled with -march=corei7. -- Olivier Smedts _ ASCII ribbon campaign ( ) e-mail: olivier@gid0.org - against HTML email & vCards X www: http://www.gid0.org - against proprietary attachments / \ "Il y a seulement 10 sortes de gens dans le monde : ceux qui comprennent le binaire, et ceux qui ne le comprennent pas."help
