Apparently this has come up before, but this is the first official bug report I've seen for it. See here on asterisk-bugs http://lists.digium.com/pipermail/asterisk-users/2015-July/287077.html
My backtrace is as follows:

The issue is the same as what is seen in the forum posting:
{noformat}
#0 ast_slinear_saturated_multiply (value=<synthetic pointer>, input=0x0)
at /usr/src/asterisk-13.11.2/include/asterisk/utils.h:369
369 res = (int) *input * *value;
(gdb) print *f
$4 = {frametype = AST_FRAME_VOICE, subclass = {integer = 0, format = 0x2310490,
frame_ending = 0}, datalen = 0, samples = 160, mallocd = 1, mallocd_hdr_len = 530,
offset = 64, src = 0x7fc268b24228 "func_jitterbuffer interpolation", data = {ptr = 0x0,
uint32 = 0, pad = "\000\000\000\000\000\000\000"}, delivery = {tv_sec = 1476225149,
tv_usec = 723471}, frame_list = {next = 0x0}, flags = 0, ts = 0, len = 0, seqno = 0}
{noformat}
This is what I have in my dialplan for volume:
{noformat}
same => n,Set(VOLUME(RX)=2)
same => n,Set(VOLUME(TX)=2)
{noformat}
This then feeds into a two-party ConfBridge with jitterbuffers enabled on both legs, but the volume Set() is only on one leg.
