18 | # Test receiving TARGET_WAITKIND_EXITED events from multiple | |
19 | # inferiors. In all stop-mode, upon receiving the exit event from one | |
20 | # of the inferiors, GDB will try to stop the other inferior, too. So, | |
21 | # a stop request will be sent. Receiving a TARGET_WAITKIND_EXITED | |
22 | # status kind as a response to that stop request instead of a | |
23 | # TARGET_WAITKIND_STOPPED should be handled by GDB without problems. | |
