Yeah, the problem with it (and pretty much all of STL) is that it has
hidden (and sometimes) unpredictable memory allocations behavior. I did some
tests recently with bcall, where different compilers does different things when
passing strings as argument to a function (one copied the string, the other did
not).
I'm ok with std::string inside the if(debug tag) if you insist. My
preference would be not to use std::string unless absolutely necessary (because
it sets bad precedence), but it's difficult to make a strong argument here
against it. :-).
