This is inside a class, right?

global.hpp should have a cpp file?  Why don't you hide myMap inside
that file.  myMap cannot be used without including myclass.hpp, so if
main.cpp does not need myclass, it would be better to split up globals.hpp
into separate files.

I don't think that you should rely on this behavior for standard 
containers, either.
