--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed.  An even simpler test case is below.  See also bug 67629.

$ cat z.c && /build/gcc-trunk-svn/gcc/xgcc -B /build/gcc-trunk-svn/gcc -S -Wall
-o/dev/null z.c
int f (void)
{
    for (int i = 1; i; )
        return 1;
}
z.c: In function ‘f’:
z.c:5:1: warning: control reaches end of non-void function [-Wreturn-type]
 }
 ^

G++ also warns on the trivial:

int f (void)
{
    if (bool b = true)
        return 1;
}
