Subject: REGISTRATION Segmentation Fault

Hello,

I am getting a Segmentation Fault after attempting to REGISTER a line (see
build configuration below).

The REGISTER request goes out and I get the "100 Trying" and "200 OK" reply
from our SIP server (see code excerpt below).  However, after a second or
two, the process encounters a Segmentation Fault and closes down the
process. The fault happens in su_root_yield() (See call flow below), and is
due to port->sup_vtable apparently getting corrupted.

I hope someone can help with this.
