This small program shows how to reproduce an abort trap (SIGABORT) when running a BLE central manager on macOS on some terminals (iTerm2).
When we removing the queue parameter in the CBCentralManager init method, that works fine.
Run make run in iTerm2.
You can run the project in Xcode but there is no crash.
