BadAccessPlayground

I'm trying to understand why this unit test (often) produces EXC_BAD_ACCESS errors. Is the code doing something unsafe? Take a look at BadAccessPlaygroundTests.swift.

Instructions

1. Open BadAccessPlayground.xcodeproj in Xcode 15
2. Run the testBadAccess() test in BadAccessPlaygroundTests.swift repeatedly until failure. Recommended 10000 max iterations.
3. Repeat until you witness a EXC_BAD_ACCESS error
