Figure out the broken CAS issue with the log globals #22

Closed jonlamb-gh closed 4 years ago

jonlamb-gh commented 4 years ago

In my setup, something is broken around intrinsic/atomic CAS, seen when using a global for the log crate: https://github.com/jonlamb-gh/log/blob/broken-cas/src/lib.rs#L1295

Using log::set_logger_racy() for the time being.
