Comment # 7
on bug 8030
from Jeff Morriss
The Valgrind script (once modified to run tshark without "-Vx") gave warnings
of this sort:
~~~

The problem was that the dissector was storing its address (AT_STRINGZ) in ep_
allocated memory. It's not the only one doing this... :-(
Fixed (at least for one dissector) in r46320.
