Wireshark-dev: [Wireshark-dev] call_dissector() is eating memory

Hello,

I am developing an application that uses libwireshark.dll to decode
packets.

The protocol of each packet is known before the dissection is started, so I
just find the needed dissector with find_dissector() and then start
dissection with call_dissector(). The code that does it is a slightly
different version of dissect_packet().

The dissection is performed multiple times a second and I've noticed
that the amount of memory that the process occupies increases with each
dissection.

In epan.c, in the epan_dissect_run() function just before the call to
dissect_packet() there's a call to ep_free_all(). If I do the same in my
function, the process stops eating memory. But the problem is that
ep_free_all() is not exported, so I have to make changes to libwireshark.def
and rebuild Wireshark each time I want to upgrade to a new version of
Wireshark.

So the question is: is ep_free_all() missing from libwireshark.def by
mistake, or is it something that I do wrong?

Thanks in advance.
