Hi Luc,

I don't think this has anything to do with boost (as Markus initially thought). This smells like over-aggressive compiler optimization after the xcode 7.3 update, I am just testing recompilation with -O2 instead of -O3 optimization.

Xcode 7.3 has no issue with Boost 1.56 for the record, which is older than the revision 86799 used by the bootstrap script if I am not mistaken.
