<pre>Code:
void foo();
void bar() {
int u;
for (int i = 0; i < 4; i++) {
if(i == 0)
u = 0;
if(u != 0)
bar();
u++;
}
}
Output:
8 : <source>:8:8: warning: variable 'u' may be uninitialized when used here
[-Wconditional-uninitialized]
if(u != 0)
^
3 : <source>:3:8: note: initialize the variable 'u' to silence this warning
int u;
^
= 0
However i think it should be pretty clear that `u` will be initialized on the
first iteration, so uninitialized `u` will never be read.
Or is this expected and a duplicate of
