Crash happens in xpressive/detail/static/compile.hpp loc 38, but only in Windows 64-bit release configuration ( any other: Linux (g++ 4.8.2,) or debug or 32-bit work just fine ). I use Visual Studio 2013 Update 4 for Win build. Addition INFO: If you build w/o NDEBUG symbol defined or if you turned off optimization it works fine. P.S. This code works fine with boost 1.51 and Visual Studio 2010. " Bugs new To Be Determined xpressive Boost 1.57.0 Problem xpressive crash
