Re: [liblo] Segfault when port is busy

Hi Alex,

I think it's probably because you're passing a C++ member function as
the error handler, which is a normal C function pointer.  Try making
it a static function.  You'll need to use the (relatively new)
lo_server_set_error_context() function if you want to pass in the
object pointer, retrieved via lo_error_get_context().

ps., feel free to test-drive the new C++ bindings!
