tsan warning for SetIsTracing #1965
Description
This came up in chromium when enabling split dwarf (no idea why that would affect tsan, but it repro's 100%).
The warning is fixed by adding ABSL_ATTRIBUTE_NO_SANITIZE_THREAD to ExecutionCoverage::SetIsTracing, but I'm not sure if that's correct, or if it should be used to use an atomic bool.
This is the commit that triggers the failure, and here is a direct link showing the tsan error.
