[Live-devel] Segmentation fault after TEARDOWN

Mon Apr 29 12:52:30 PDT 2013

I unfortunately don't have much more info, but I believe I also experience
this issue.

Last week I upgraded from 2013.03.07 to 2013.04.23 and we suddenly started
to experience program crashes (liveMedia used within a DLL in Windows client
streaming mjpeg). I didn't suspect the liveMedia update at first, since we
also had made some other changes, but when I saw your message I reverted
back to 2013.03.07 and now everything seems to work as before.

Hi guys,

I got the exact same crash today while testing RTSP over TCP, I can see that
the root cause seems to come from file RTPInterface.cpp in
SocketDescriptor::tcpReadHandler() (line 406).  There is a while loop that
was not there before and it finally crash in Groupsock while looping this
code.  I don't have time now to give more info but I can provider a better
call stack later if needed.

Hello,

I've update to the last version of the live555 library (2013.04.23) and 've
experiencing a problem that doesn't appear in previous versions. After a
TEARDOWN sent by the client, the software crashes with a segmentation fault.

I've reproduced the problem with the live555ProxyServer (I send attached the
application log).You can see that after a TEARDOWN sent by the client, the
proxy server tries to execute the
"ProxyServerMediaSubsession["H264"]::closeStreamSource()", and then the
segmentation fault occurs.
I don't know whats happening, but with the 2013.04.01 version doesn't
happen.
It seems that any change in the last version causes this issue
I would be grateful if someone could help me with this
