  • SR-12601 Address Sanitizer's leak output not symbolicated

Issue Description:

The attached project leaks 100 objects when running the tests.

When running on macOS with Swift 5.0, it correctly reports the leak (amongst other noise/leaks in XCTests but that's a different issue) with nice symbolication:

I didn't think we got any symbolication on Linux. Am I just misremembering?

@belkadan that's correct for fatalErrors and the like but I couldn't remember what the sanitizer situation was...
