Presumably it is then up to subclass to actually fill in this pointer and set
up corresponding area, in which case that is one approach.

A simplified version would be a flag (e.g.)
GST_BASE_PARSE_FRAME_FLAG_SEEN_FRAME, that could be set by subclass whenever it
stores some state data, and this flag not being set is a sign to clear any
state data (in the case above, pointer == NULL then serves as such as a
"sign").

The former is more general/cleaner, the simpler approach entails less bloat for
the subclass and might avoid some additional alloc/free.
