--- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> ---
Hopefully reduced to something reasonable:
$ cat pr57832.c
int a, b, d;
void f() {
unsigned c;
for (int e = 0; e < 64; e += 6) {
b = e ?: (c = d);
a += e ? 9 + c + e : 0;
}
}
$ gcc -mtune=atom -O2 -Werror=maybe-uninitialized pr57832.c -c
pr57832.c: In function ‘f’:
pr57832.c:3:12: error: ‘c’ may be used uninitialized in this function
[-Werror=maybe-uninitialized]
unsigned c;
^
cc1: some warnings being treated as errors
$ gcc -O2 -Werror=maybe-uninitialized pr57832.c -c
[nothing]
