[PATCH] D58221: [msan] Don't delete MSanAtExitRecord

[Peter Smith via Phabricator via llvm-commits]

peter.smith added a comment.

The test added here is intermittently hanging on our AArch64 buildbot.

This can either manifest itself as a the whole step timing out, or the test failing:

- http://lab.llvm.org:8011/builders/clang-cmake-aarch64-lld/builds/6060/steps/ninja%20check%202/logs/stdio (ninja check-all failing).
- http://lab.llvm.org:8011/builders/clang-cmake-aarch64-lld/builds/6057 (failing)

By running just the test continuously on an Ubuntu 16.04 machine I can get it to hang. The machine seems to need to be heavily loaded before this happens though. I've tried on another Ubuntu 16.04 machine that isn't loaded and I can't get it to hang. On the face of it, it looks like whatever fix worked for x86 hasn't worked for AArch64. Have you any suggestions on how to proceed? The obvious solution is to disable the test on AArch64, but this may just be hiding the problem?
