When running on Windows in Debug mode, the code terminates with exit code -2147483645. No error message is printed. Occasionally a message similar to the following is emitted:

Error: Failed to send request: {"jsonrpc":"2.0","id":"9","method":"setExceptionPauseMode","params":{"isolateId":"isolates/3021199231267163","mode":"Unhandled"}}

(I counter the message just once in tens of the executions.)
