 What happens if you access v[2]??

 The other (potentially independent) question is what v[42] does. Is the
 vector extended to contain 43 elements or does the core just access a non-
 existent element and thus just gets some random data back? Your output
 looks like its the latter case.

 Maybe the goal for 2.1 should be to do a complete overhaul/redesign of
 list / vector functionality in Bro. I.e., lets discuss what functionality
 makes sense and then implement that. IIRC, the current functionality is
 inconsistent and partially broken. And I think vectors are hardly used, so
 it shouldn't be too painful to adapt script level code.
