These events are identified in their spec by the HasData flag.

The second special case consists of stack events. These events are identified
by the IsStack flag. These events also have a trailing unsigned integer argument
describing the number of stack frame descriptors that follow. Each stack frame
descriptor is on its own line following the event, consisting of four signed
