Segfault with default config file #116

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. install the server with the deps package
2. run the server with the default config
3. see the seg fault occur

the problem comes with the <sip-transport> data in the sip-uas tag in the xml 
config.  Putting one of both transport (udp or tcp) works, but not when both 
are specified "tcp,udp".

This segfault occurs in the method su_casematch called from 
tport_server_addrinfo in the file tport.c from sofia-sip

This problem occurs on an ubuntu server 10.10 installation with default 
installation packages.

As we talked, I attaching my installation procedure and a resume of my 
configuration.  I'm still have problems with Asterisk->UniMRCP->PocketSphinx 
communication but I haven't a segmentatio fault :-)

my installation is in a Centos 5.4 box so double check every step before 
applying it

I hope this helps !

Honestly speaking, this looks like some sort of hidden bug in Sofia-SIP. I'm 
wondering if you can run the same with valgrind and provide output. Another 
thing you may try is to use the latest Sofia-SIP library instead of the one 
included in the UniMRCP dependency package to see if it makes any difference.

I believe I have encountered the same problem recently. Below is the fix which 
will be available in the upcoming release of the dependencies (Sofia-SIP).

If you look into the function nta_agent_add_tport(), it'll become clear that 
the variable tps[] MUST have been declared at least at the same level (scope) 
as the variable tport; otherwise, it could easily cause Sofia-SIP to crash.
