Pretty please, before filing further bugs take time and learn C.
The pointer subtraction triggers undefined behavior, because one pointer points
to one object and the other pointer points to different object.
See ISO C99, 6.5.6/9.
In particular, in this testcase the functions are inlined and thus i and strp
are just normal automatic variables in main, obviously nothing guarantees how
they are laid out in the stack. But even if it isn't inlined, the behavior
would be undefined.
