Hi there,
I'm seeing constant nua crashes when my application is under traffic.
I always get the following backtrace after the SIGSEGV:

(gdb) p ss
$1 = (nua_session_usage_t *) 0x0
(gdb)
Considering that there are only sofia addresses in the trace, is this
an internal sofia bug or is it possible that my application is
misbehaving and causing the crash?
This is on vanilla 1.12.7 minus the patch that caused the memory leaks.
Thanks in advance.
