I've managed to reproduce that compiler error with gcc 4.1.0. I know that it is 
not a supported platform, but maybe you are interested on this.

The code can be found here: http://usalug.org/pastebin/pastebin.php?show=392

The full compiler error was (gcc 4.1.0):

of 'default_state<int>':

The same code can be compiled with gcc 3.2.3 just fine.
