Comment(by ionic@…):

 Oh don't get me started. Both _GLIBCXX_DEBUG and _GLIBCXX_DEBUG_PEDANTIC
 are broken on OS X and must '''always be disabled'''.

 I had to learn the hard way through weird bugs and random crashes. Added
 "-U_GLIBCXX_DEBUG -U_GLIBCXX_DEBUG_PEDANTIC" as CXXFLAGS to my project and
 haven't had a problem like this since.

 Yeah, a likely cause of trouble... I totally forgot about those two
 macros, sorry.
