reentrant_init test failure with --all-targets #79

Closed tsipinakis closed 4 years ago

tsipinakis commented 4 years ago

Greetings, and happy new year!

The test suite appears to fail in the sync::reentrant_init test when run with cargo test --all-targets (but doesn't with just cargo test).

The stack trace is as follows:
