I think that this sounds very much like an optimizer bug and the way to 
understand what's going on is to submit a bug report to the GCC bugzilla. It 
could, in principle, be an aliasing violation issue in boost::function, but 
I doubt it. g++ since 4.4 is getting more aggressive with its aliasing 
assumptions when optimizing.
