[PATCH] D35443: Enable 64-bit Darwin LeakSanitizer by default on AddressSanitizer builds

[Francis Ricci via Phabricator via llvm-commits]

fjricci added a comment.

Still working on swift, but looks like bootstrapped llvm-tblgen has a few leaks. They don't show up on Linux, but they also don't really look like false positives:

Direct leak of 61440 byte(s) in 256 object(s) allocated from:
