C11 states, page 12, section 5.1.2.2:
"All objects of static storage duration shell be initialized (set to
their initial values) before program startup. The manner and timing of
such initializations are otherwise unspecified."
In this case, as defined in 6.2.4, "static" just means always allocated
(not on the stack, etc.).
So, IMHO, you can't expect zeros.
