Thanks for your report. So this issue also happens with GCC 4.3.2? Max  
was using GCC 3.2.2 for PS2...

Is the 68k target still actively supported by the GCC folks? If so, it  
might be a good idea to file a bug report about this. The Hashmap code  
is fairly isolated, so it shouldn't be difficult to generate a  
"minimal" code example from this. Keith, can you do that? You can find  
instructions for this on <http://gcc.gnu.org/bugs.html>;  if you need  
advice/assistance, ping me.

This error is quite different from the one Max got in GCC 3.2.2, and  
even occurs in a different line in hashmap.h, so they might not be  
related, given that the two GCC versions are also radically different,  
and so are the target CPUs.


Cheers,
Max
