[Bug c/40469] New: [4.3/4.4/4.5 Regression] "Missing" uninitialized warning

[hp at gcc dot gnu dot org]

Compiling the following code with -O2 -W -Wall, gcc-3.2 gives a warning:
p.c: In function `bar':
p.c:4: warning: `res' might be used uninitialized in this function

No open branch does, anymore.

p.c:
int
bar(int foo)
{
  int res;

  if (foo) {
  } else {
    res = 0;
  }

  return res;
}

int
main()
{
  return bar(1);
}

This PR seems similar to PR22456, but this code isn't a loop.
If it really is the same, I guess WONTFIX.
