> During a call when the caller send a DTMF (using the method negotiated in SDP and configured for the peer) asterisk ends with SIGSEGV.
> The versions I tested (using chan_sip) were :
> * 16.2.1 with debian patches (which we are using at the moment), no crash,
> * 16.6.0 with debian patches, no crash,
> * 16.7.0/16.8.0/16.9.0 with debian patches, segfault,
> * 16.9.0 built from upstream archive without packaging nor patches, segfault.
> The crash happens while playing a .wav or in a call or with Answer+Echo.
> It happens either before the call is answered or after.
> It happens with dtmfmode set 2833 of info.
