[asterisk-users] Issues with Siren14 codec in Asterisk 14.3.0

[Richard Kenner]

I'm seeing Asterisk crashes with the following frame at func_speex.c:188:

(gdb) p *frame
$6 = {frametype = AST_FRAME_VOICE, subclass = {integer = 0, 
    format = 0xe2f9e20, frame_ending = 0}, datalen = 0, samples = 640, 
  mallocd = 1, mallocd_hdr_len = 232, offset = 64, 
  src = 0x2ac07413e7f8 "siren14tolin32", data = {ptr = 0x3cab9378, 
    uint32 = 1017877368, pad = "x\223\253<\000\000\000"}, delivery = {
    tv_sec = 1491485582, tv_usec = 407272}, frame_list = {next = 0x0}, 
  flags = 0, ts = 0, len = 0, seqno = 0}

frame->data.ptr is an out-of-range address.

Does this ring a bell to anybody?  Without sources of the Siren14 codec,
how would you recommend we debug this?
