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.
