Comment:

 I managed to reproduce the error, after I upgraded to Kubuntu 14.04 and
 tried to compile Boost with -march=native on a Sandy Bridge machine. The
 patch I attached earlier does not help. For now I have no further ideas
 how to work it around and make -march=native work, the issue has to be
 fixed in gcc.

 Considering that even when the compilation succeeds (i.e. -march=native is
 not used) the resulting binaries are incorrect, I'll document gcc LTO as
 unsupported.
