`qthread_disable_shepherd` Crashes Intermittently With Thread Sanitizer Enabled #232

Closed insertinterestingnamehere closed 2 weeks ago

insertinterestingnamehere commented 9 months ago

Running on x86 with clang17, nemesis scheduler, no topology detection, and thread sanitizer enabled, the qthread_disable_shepherd test crashes intermittently. Unfortunately this only happens outside the debugger so more work is needed to find where exactly the segfault is happening.

Same thing was going on with syncvar_prodcons. Just added a commit that resolves this in #235.

Nevermind. It was just intermittent enough to look solved. The syncvar_prodcons intermittent failure is fixed though. Still investigating.

This hasn't been happening for a long while. Tentatively closing.
