--- Comment #1 from Xi Ruoyao <xry111 at gcc dot gnu.org> ---
Isn't this a UB?
while (p >= path && *p != '/')
p--;
This will cause p to become "&main::path[0] - 1". C23 6.5.6p9:
If the pointer operand and the result do not point to elements of the same
array object or one past the last element of the array object, the behavior is
undefined.
