[llvm-commits] [patch] More strict checking in LeakDetectorImpl::addGarbage

[Rafael Espindola]

Currently we assert in  LeakDetectorImpl::addGarbage that we don't
mark something as garbage twice. Unfortunately, as the comments in the
file say, we do so only in the uncommon case "by far" :-(

The attached patch adds a similar check for the common case. This
makes PR5790 much easier to reproduce and probably helps PR5770 too.

Tested with a "make check-lit". No unexpected failures.

OK for trunk?

Cheers,
