Expected behavior

Doesn't crash

Environment

Works:

Swift version 5.10.1 (swift-5.10.1-RELEASE)
Target: aarch64-unknown-linux-gnu

Fails:

Swift version 5.10.1 (swift-5.10.1-RELEASE)
Target: x86_64-unknown-linux-gnu

Additional information

No response

lhoward commented 3 weeks ago

It appears the offending code is this in the initialiser:

    _leaveAll = await LeaveAll(
      interval: controller.leaveAllTime,
      onLeaveAllTimerExpired: _onLeaveAllTimerExpired
    )

investigating further.

lhoward commented 3 weeks ago

OK, if I move the initialisation of _leaveAll into a separate async function which is called from the initialiser, the compile no longer crashes.
