The GObject documentation notes that the "func" argument which is "The C closure callback of the handlers" of g_signal_handlers_[un]block_by_func(instance, func, data) is "useless for non-C closures". Does that mean the way "func" is handled changes with a different type of compiler?
No, there are actually two types of closures, GClosure, which is a generic closure that might be implemented in any number of languages, and GCClosure, which is designed specifically to be a binding for a C (or C++) callback function.
In any case, problem is that the GCClosure code is actually violating the ANSI C specification and making non-portable assumptions. See my other message.
