In theory, the dictionaries passed to functions could always be passed by value. -fdicts-strict is supposed to make this happen, which should make overloaded programs a bit more efficient. I don't think it's ever been tested, though, so I'm not surprised it doesn't work properly. If you can make a reasonably small program that demonstrates the failure I'd be happy to look at it.
