[ filesystem ] 1.45 broken on gcc 4.5 on AIX 5.3
OK I realise AIX/gcc is not really a supported platform? But in boost 1.45 the file system causes a crash. My understanding was that at 1.45 the file system v2 was the default ? However looking at the stack trace it appears that at start up file system v3 make use of a static object to set the locale(), see file path.cpp namespace boost { namespace filesystem3 { const path::codecvt_type *& path::wchar_t_codecvt_facet() { static const std::codecvt<wchar_t, char, std::mbstate_t> * facet( &std::use_facet<std::codecvt<wchar_t, char, std::mbstate_t> > (path_locale())); return facet; } ..... path_locale() ends up calling default_locale(), which call's std::locale("") In std::locale() for some reason the locale can not be created and an exception is thrown. This exception has no chance of being caught since it called before main(). See the totalview trace back below: The work around appears to be to set the environment variable LANG to an empty string. Have not tested this on boost 1.46, but I suspect the same problem.
