Yes I found them on coverity as I wanted to find out how bad their
false positives are these days. So I looked at the most recent findings.

I somehow imagined that we could redefine the _INIT macros which
usually lead to false positives (just alloc&UNLEAK memory instead of
pointing them all at the same memory for _INIT), but that experiment
did not work out.
