[meta-freescale] gst-launch-1.0 segmentation Fault

[Mohammad, Jamal M]

Hi,
We are using gst-launch in our application to stream the CSI over Display whenever it detects Signal and Stop the Streamer when there is no signal.. To find out whether gst-launch works well with many connects/disconnects, i was testing gst-launch functionality with the following simple code:
void MainLoop()
{
   char command[256];
   int ret = 0;
   int loopCount = 0;
   while(1)
   {
      memset(command, '\0', sizeof(command));
      sprintf(command, "/usr/bin/gst-launch-1.0 imxv4l2videosrc ! imxipuvideosink &");
      ret = system(command);
      printf("StartStreamer: command=[%s], status:%d\n", command, ret);
      sleep(15);
      memset(command, '\0', sizeof(command));
      sprintf(command, "killall gst-launch-1.0");
      ret = system(command);
      printf("StopStreamer: command=[%s], status = %d\n", command, ret);
      sleep(15);
      loopCount++;
      printf("Loop Count:%d\n", loopCount);
      fflush(stdout);
   }
}

After running a loop count of about 2400+ it failed with segmentation Fault, in the next restart of the utility, it crashed at 551 Loop Count and then at 1300+ Loop Count..
Following is the Log at the stdout before segmentation Fault:

[1]+ Segmentation fault ./startStop
I believe it is due to some memory corruption .. How can we resolve this issue...
