Little addition: -O3 works fine with address-model=64 (-m64) but fails with address-model=32 (-m32)

There is a high chance you cannot reproduce this bug, because the gcc-5666.3 I'm using is not 100% from Apple, it is a crosscompiler with patch applied on it, for example I couldn't generate muliarch fat binaries due to a bug in the cross compiler version on Windows

When if you can't reproduce this on the official gcc-5666.3 then disregard and close this ticket because won't be fixable on your end.

Boost C++ Libraries: Ticket #9791: [libs/program_options] winmain.cpp fails to compile with -O3, ok with -O0 (gcc-5666.3)
