[Bug bootstrap/43921] New: Bootstrap comparison fails when using -march=atom

[nisselarsson at home dot se]

When I try to build gcc-4.5 with gcc-4.5 using -march=atom it fails when
comparing stage2 and 3:

Initially gcc-4.5 was built with gcc-4.4.3 using -march=core2 -mtune=generic.

This is my first GCC bug report so I'm not sure what else I need to provide.
