--- Comment #4 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- I'm sure that bug is already filled and analyzed, but I cannot find it right now. The problem there (and probably here) is that a && b is converted to a & b, and b is uninitialized if and only if (a == 0) but the uninit pass is not smart enough to realize this.
