Not until it is dereferenced. Consider that it might be put into
a database field or a collection. Then the effect of the error is
discovered two or three steps away from where it is actually located,
which is great if you enjoy debugging.

(Please don't forget that this is probably by far the most common source
of runtime errors in programming languages that don't have exceptions.)
