std::string weird error

[Ondrej Stastny <StastnyO gmail com>]

Hello! I'm tryig to get to run a GTKmm and libglademm app, but I have a 
really weird issue with std::string. I'm under Win XP, MSVC++ 8 Beta 2. 
I have both GTK+ and GTKmm correctly installed .
When I try to run simple program below It starts printing out weird 
strings such as some dll paths and other system related things all 
joined in one huge string and the computer is beeping on the top of it.
I don't need to include gtkmm.h either as it's enought to link gtkmm 
related libraries to produce this error. What could be a problem?

#include <iostream>
#include <string>
#include <gtkmm.h>

int main(int argc, char *argv[]) {
   std::string str("ui.glade");
   std::cout << str << std::endl;
}
