Coturn breaks with a segfault error

[Sevryukov Oleg]

1)OS:
Description: Ubuntu 16.04.3 LTS
Release: 16.04

2) Coturn version:
coturn:
  Installed: 4.5.0.3-1build1
  Candidate: 4.5.0.3-1build1
  Version table:
 *** 4.5.0.3-1build1 500
        500 http://us-east-1.ec2.archive.ubuntu.com/ubuntu xenial/universe amd64 Packages
        100 /var/lib/dpkg/status

3) It should work correctly
4) When somebody does http requests coturn fails with a segfault error:

kernel: [86289.872427] turnserver[7122]: segfault at 8 ip 000055ec3455d9b2 sp 00007f8bc99b9cf0 error 6 in turnserver[55ec3454b000+6a000]

Looks like this bug was fixed in the newest coturn versions, but they don't available for the Ubuntu Xenial.
