--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
Another test case for the same underlying bug.
$ cat z.c && gcc -O2 -S -Wall z.c
void f (const int*, const int*);
void g (void)
{
int a = 0, b;
f (&a, &b);
}
void h (void)
{
int a = 0, b;
f (&a, 0);
f (&b, 0);
}
z.c: In function ‘g’:
z.c:6:3: warning: ‘b’ may be used uninitialized [-Wmaybe-uninitialized]
6 | f (&a, &b);
| ^~~~~~~~~~
z.c:1:6: note: by argument 2 of type ‘const int *’ to ‘f’ declared here
1 | void f (const int*, const int*);
| ^
z.c:5:14: note: ‘b’ declared here
5 | int a = 0, b;
