I suspect I'm dealing with memory corruption somewhere in my program. I'm getting a SIGSEGV on a call to a function from a trusted third-party library. With some trial and error I've discovered that this segfault happens when the lines

Qt Code: 
  1. emit newStreamFound(_streams[streamOneSSRC]);
  2. emit newStreamFound(_streams[streamTwoSSRC]);

are not commented. This happens even when no slots are connected to this signal. As far as I know there are no thread safety issues. I ran a Valgrind memory analysis with these lines disabled and this is what came up:



I can't make heads or tails of this output. The test condition in the do while loop depends on one variable that is, in fact, initialized at the top of the function. Does any of this point to issues that should be investigated? If not, what are the next steps I can take?
