In the last backtrace I sent, I forgot to install debug symbols on the included libs, so here's another backtrace from a memory-error core dump with all the debug symbols available.
After the first listing, there's another listing from a stream that hung, which seems to be an alternate behavior of gst123 when the stream isn't causing memory corruption/core dump behavior. In the "hang" case, you see the time-elapsed counter staying fixed, and the process just spins; which is a different behavior than if the stream were to be interrupted -- which terminates correctly and doesn't "spin." The latter backtrace is from a SIGINT on the spinning process but should at least indicate where it was spinning.
