There are few incompatibilities in the standard library. They are documented 
there: http://gcc.gnu.org/wiki/Cxx11AbiCompatibility

Fortunately, Qt does not use any of the problematic API. So it should work 
without problem: You can safaly develop your application in C++11 and link 
against a Qt compiled using C++98 and the other way around.

I'm not aware of any problem with std::string. I don't understand your 
comment.  Using std::string should remain safe.
