I'd suggest changing this interface from void ** to more typed pointers to catch this, although I'd expect GCC/Clang to catch passing a void * to void ** parameter. Maybe check WARNS level?

I think eventually we need there a bit more generic buffer structure to allow custom alignment, but that idea needs more time to settle.
