Thanks for this link.

So the bug report is that the file below is rejected by GCC 9.1 (and every GCC
version present on Compiler Explorer down to 4.1.2), whereas according to the
arguments in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=14366 it should be
accepted.

int *p1, *p2;

static int i = 1;

void f(void) {
    p1 = &i;
    int i = 2;
    {
        extern int i;
        p2 = &i;
    }
}
