Also happens when holding the frame advance key. Like JMC just mentioned, 5.0-10607 makes it so that it only happens if you have the debugger enabled, but this isn't a proper fix for the issue.
Dolphin doesn't necessarily always freeze or crash from the testing I've done, but the GUI gets unresponsive due to the large number of backlogged EmulationStateChanged events, and sooner or later you usually get an "Unable to resolve read address" panic alert with the following stack trace:
