i'm talking about stack corruption
does double get coerced to int?
if so, 4 bytes are pushed to the stack
what code does this implicit definition contain?
e.g., does it return something at all? or only pops args back?
if it pops, doesn't it pop 4 bytes?
i don't see why the stack gets corrupted
why do you think such thing got in the standard?
i mean, what's useful in such dangerous things?

<p>also, gcc picks up printf definition from somewhere (and does printf right), even if i don't include <stdio.h>
isn't that bad?
i may forget about <stdio.h>, and other compiler will fail (or is there smth in the standard about this?)
