Attached.

PS. I'd rather want to hear comments, rather than debugging...


I would be in favour of having having the trunk build fail (hopefully with a useful warning) whenever someone accesses ep memory after dissection of the packet has finished.  Hopefully there won't be too many places where it is still being accessed late and problems can be fixed quickly.  The only place I've seen so far is tcp_graph.c (and rlc_lte_graph.c, which had copied the same approach to identifying the stream/channel by dissecting just the currently selected frame).  I did review a couple of other taps but didn't see the same problem.
