Sorry, I've made mistake trying to simplify the test case.

Is it still correct to generate warning for the code below?

int error(void);
int baz(char **, const char *);
int quux(char *);

static int bar(char **out, const char *in)
{
    char *t;
    int err;

    err = baz(&t, in);
    if (err < 0)
        return error();

    *out = t;

    return 0;
}

int foo(const char *a)
{
    int err;
    char *b;

    err = bar(&b, a);
    if (err < 0)
        return error();

    return quux(b);
}
