Complete example is 10 lines. You should see "abab", but you'll get "ab". BUT if you redirect the output/error into a file, the file will get "abab". So make sure you run with the console/terminal being the stdout/stderr. >Fix: None know. Looked in the Cygwin source, discovered there is some special treatment of consoles for stdout, stderr, but didn't figure out a fix. >Release-Note: >Audit-Trail: >Unformatted: ----gnatsweb-attachment---- Content-Type: application/x-zip-compressed; name="jni.zip" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="jni.zip" UEsDBBQAAAAIAHxV+yotFUZ7egAAAPsAAAAQAAAAam5pL0ludm9rZXIuamF2YSsoTcrJTFZIzkks LlbwzCvLz04t4uWq5uVSAILiksQSoGRZfmaKQm5iZp5GcElRZl56dKxCYlF6sSZEEVQtCARXFpek 5uqlFhXpFQAVluTkaSglKmlaY6jILy1BqEjCpiInPzHFJzOpKLGoEqgiMQWbGrLtqeXlAiIAUEsD BBQAAAAIAG5W+yppaHeLXgAAAHYAAAAOAAAAam5pL21ha2VpdC5iYXQ1yEEOgyAQBdC9iXeYvf3c wxO4/gyTFkVoEIm9fdM0Lt/TaRIcL1YLgiU9ALvepTaET+Ye9c5Mnww8W0Hc+TR4HiYo4hlcSEky W+zmVMdhZafKnHvZrLqf/nfXOHwBUEsDBAoAAAAAAHJV+yqdo1UjKAAAACgAAAANAAAAam5pL25h dGl2ZS5jY19fZGVjbHNwZWMgKGRsbGV4cG9ydCkgaW50IGFueSgpDQp7DQp9DQpQSwMECgAAAAAA c1b7KgAAAAAAAAAAAAAAAAQAAABqbmkvUEsBAhQAFAAAAAgAfFX7Ki0VRnt6AAAA+wAAABAAAAAA AAAAAQAgALaBAAAAAGpuaS9JbnZva2VyLmphdmFQSwECFAAUAAAACABuVvsqaWh3i14AAAB2AAAA DgAAAAAAAAABACAA/4GoAAAAam5pL21ha2VpdC5iYXRQSwECFAAKAAAAAAByVfsqnaNVIygAAAAo AAAADQAAAAAAAAABACAAtoEyAQAAam5pL25hdGl2ZS5jY1BLAQIUAAoAAAAAAHNW+yoAAAAAAAAA AAAAAAAEAAAAAAAAAAAAEAD/QYUBAABqbmkvUEsFBgAAAAAEAAQA5wAAAKcBAAAAAA==
