[Bug c/19430] New: Missing warning

[terra at gnome dot org]

the program below should result in a warning that "j" might be used
uninitialized.  If the "baz" call is replaced with an explicit assignment
to "j" a warning is generated as expected.

> gcc-3.4.2 -c -Wall -O2 ~/foo.c
(stunning silence)


extern int bar (int);
extern void baz (int *);

int
foo (int i)
{
  int j;

  if (bar (i)) {
    // These should do the same with respect to `j':
    baz (&j);
    // j = 1;
  } else {
  }

  return j;
}
