Please see #24869. Atlas seems to require gcc45 (gcc44?) in order to work properly on Arrandale CPUs.

I'm currently building on my new macbook i7 with gcc45, if it builds I'll make 4.5 the default variant and close the ticket.

Resolution: fixed
Status: newclosed

Ok, I had a malfunction with my macbook (power cable thing). Anyway, I didnt' finish the build on that platform. However, atlas builds fine with gcc45 on my Mac Pro, so I've added the gcc45 variant, set it as default, and pushing the changes.

Please don't make gcc45 the default variant except in the specific cases where you are sure it's needed. We don't want to end up with #25081 all over again.
