int baz(char **, const char *);
int quux(char *);
int foo(const char *a)
{
char *b;
int t1;
{
char *t;
if (!baz(&t, a))
t1 = -1
b = t;
t1 = 0;
}
if (!t1)
return -1;
return quux(b);
}
--- CUT ---
After some more optimization:
int foo(const char *a)
{
char *b;
char *t;
if (!baz(&t, a))
;
else
return -1;
return quux(b);
}
looks like a correct uninitialized warning to me after inlinining has happened.
b is initialized when the return value (t1) is 0 and uninitialized otherwise.
