This sounds like something wmem could solve - if there is an

Yeah, I thought so too but I took the quick way out (to shut the
buildbot up).
Is the needed scope for these addresses well defined?
I'm not entirely sure, but it is (apparently) at least the old ep_
scope (in that the memory needs to be around at least until we *start*
dissecting the next packet). At least one of the dissectors I looked
at used (non-static!) local variables to hold their AT_STRINGZ. :-(
Ouch.
I'm not sure either, but I think the addresses might need to stick
around a little longer than that - maybe the length of the current
dissection (ie until the file is loaded or the filter has finished
running etc). That strikes me as a nice middle-ground between ep and
se, although it may be unnecessarily long for this particular case.
Where exactly were the addresses being used that was after the ep
memory was freed?
