The C standard is very explicit about not doing this;
see subclauses 7.1.3 and 7.1.4.
What you have is not a strictly conforming program,
so its lack of success with a particular C implementation
does not indicate that the C implementation is not conforming.

It might be surprising that programmers need to be more careful,
but there are many aspects of C like that.
