--- Comment #3 from Steffen Hau <steffen at hauihau dot de> ---
I can confirm that replaceing -march=native with -march=corei7-avx solves the
issue and boost compiles fine afterwards.

Is a testcase still needed? I have no idea how to strip down the affected boost
module to reproduce the issue. The developer is not able to reproduce the but
he had another idea with adding target attributes to some functions to give gcc
some hints. I'll try to compile boost with his patch and march=native to see if
that helps. I've added the boost bug as reference.
