Created attachment 302377 [details] build log On my hardened ~amd64 machine with gcc-4.6.2 I see the following test failure for gsl. I can try testing this for the main-tree variant too, but there is a blocker which I would fight only if necessary.

Could you try with simpler CFLAGS, such as -O2 -march=native?
Okay, this seems to have nailed it. With CFLAGS="-O2 -pipe -march=native" I see a different failure later on. With CFLAGS="-O2 -pipe -march=native -floop-strip-mine" I see the first failure again.
