Segmentation fault. on tcp relay

[GoogleCodeExporter]

I found SEGV in tcp relay. ( turnserver-3.1.1.0)

should check which ss is not null  before  ss->enforce_fingerprints? 

following gdb console log.
(gdb) c
Continuing.

Program received signal SIGSEGV, Segmentation fault.

The fix can be taken from SVN, for now. Later it will be included into a 
subsequent release.
