Nice to know, but I was talking on things like the *context
in that funcion.
Even only temporarily valies, if set to a certain value,
like 0 or NULL, will help in finding problems.
The mentioned function just was an example.
Uninitialzed values I see nearly everywhere in the code.
Dereferencing NULL is easy to find, because it crashes early.
