Dunno. I didn't know these existed. Thanks for pointing it out.
Right now I'm shaking off false positives by bootstrapping with
-Wuninitialized. Once I'm confident it's more or less stable, I
will add the flag to the regression tests.
First I need to disable the original warning, otherwise we won't
know which of the two are emitting the warning.
