classic. you can't take the address of a va_list, it will fail in very
different manners on different platforms/architectures. This means you
can't call va_arg() on different functions passing the arg around.
Unless you use some hacks. There's a hack that works pretty well. See
macro MAKE_PTR_FROM_VA_LIST() in edbus.

A bit of info on the commit that introduced that macro:
