[sr-dev] segfault with t_suspend() / t_continue()

[Dragos Oancea]

Hi Daniel,

Here is the output of `bt full`:

Let me know if I can be of any assistance further.

Regards,
Dragos

Hello,

could be related, but the issue seems to be while processing a SIP
    reply, not with suspend/continue of a request. Can you send the

Cheers,
Daniel
