Microsoft's and Sun's compilers would be more likely to run into issues, particularly Sun's; Sun has had a policy of preferring solid backward compatibility to standards compliance, so I've tended to have more problems getting correct, standard C++ to run on their compiler than on others. This is particularly true of template-based code and nested classes.
