[Live-devel] SIGSEGV Exception After sendDescribeCommand() Called

[Peter McCarthy]

Hi Ross,

I'm developing a prototype Android app (Nexus 7, Jelly Bean 4.3) which 
uses some source code based on the testRTSPClient.cpp sample.

The app currently uses the Live555 release dated 2013-10-03 and it works 
very reliably. However, if I then use any release after that date 
(including 2014-01-11), the app immediately throws a SIGSEGV exception.

Now, this happens sometime after sendDescribeCommand(), but before 
continueAfterDESCRIBE() , is called.

I've included an abbreviated dump of the exception below:

Have you got any ideas as to why this is happening? Thanks in advance 
for your help.
