Comment (by bgschaid@…):

 Well. I'd beg to differ: I didn't say it in the original posting but my
 machine is an Corei5.

 Maybe it is even worse: a previous version (the original problem was 6
 weeks ago) of LLVM/CLang had that problem on i5. Now they "fixed" it and
 something similar pops up on i7. There seems to be more development going
 on on the CLang side that on the Gcc-side ... which is not always a good
 thing.

 As long as CLang is such a moving target I'd suggest to err onto the side
 of lower performance (but higher stability) and set a stable compiler
 suite as the default settings. Those who really need the performance of
 Atlas (and don't just install it because it is the dependency for some
 other package) can always set that variant
