Build Information:

Discovered while poking through bug #8467 (itself a byproduct of bug #8461).
The *_idx functions in value_string.c can set the index to -1. There are
several places where these values are being used directly as array indices
without first checking for -1.

The one that caught my eye was packet-gsm_a_dtap.c around line 6432, but there
are others. Discussed briefly on -dev at:
