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.
Ouch. I'll report to GCC then.
Thanks. I'm trying to retrieve the password for my Bugzilla account - with no luck so far. You may want to relay to Richard that after stepping through the code, it turns out that function_buffer is indeed assigned directly, due to the fact that __has_trivial_copy and __has_trivial_destructor report true for the stored function object.
