Comment:

 You must use the same standard library implementation used by boost when
 compiling your own executables. On Mountain Lion, MacPorts builds boost
 against libstdc++ (which is the default on this OS). If you use this
 version of boost in an executable compiled with `clang++ -std=c++11
 -stdlib=libc++` the generated executable will link against both
 `/usr/lib/libc++.1.dylib` and `/usr/lib/libstdc++.6.dylib` which
 '''will''' lead to undefined behavior and crashes, as you have seen.

 If you want to use C++11 on Mountain Lion, you'll have to compile boost
 against libc++ on your own. See also
 https://lists.macosforge.org/pipermail/macports-
 dev/2013-December/025360.html which describes the issue in more detail and
 outlines possible solutions (none of which have been implemented in
 MacPorts due to lack of manpower).
