The problem is not in gcc, but somewhere in std/crt. The exception is
thrown by std::use_facet() function, which doesn't find the locale you
passed to trim(). Since, you don't actually pass any locale, it uses
the global one, so I don't understand why it doesn't find it...
Anyway, try passing some locale explicitly, and see what happens:
boost::trim(str, std::locale("English_UK"));
