The following doesn't compile with gcc 4.3.2 on Linux x86:

#include <iostream>
#include <boost/algorithm/string.hpp>
#include <boost/asio/ip/udp.hpp>

int main( void )
{
     std::cout << "Oh dear..." << std::endl;
     return 0;
}

Note this is just a minimal example, the error occurred while trying to 
compile a real world application
where the boost header you see here get included in different modules.
When I change the order of the header (include udp.hpp before 
string.hpp) the code compiles just fine.
The error is:
