Please, help me to remind...
If a local variable is declared but not set to any value, does it take
space on the stack?
If I understand your message, it does not. Therefore it is only declared
but no memory is allocated for it (i.e., it is not instantiated). Right?
If you confirm I've understood this topic, I can send a v2 patch.
Thanks for your review,
