The newly added testcase only failed on [AddressSanitizer-x86_64-darwin](https://green.lab.llvm.org/job/llvm.org/job/clang-stage1-cmake-RA-expensive/3965/testReport/AddressSanitizer-x86_64-darwin/).

The test failed due to a timeout, and it seems that in that environment, the deadlock problem of the test case has not been resolved, and the built-in WatchDog thread did not kill the test process normally.

I'm looking for a Darwin machine to determine what is happening.
