If you compile with address sanitizer you get this error for

This happens inside the guts of GStreamer. If compiling without the
sanitizer and running under gdb you get this:

60 ret = gst_element_get_state(pipeline.get(), nullptr, nullptr,
3*GST_SECOND);
Meaning that GStreamer dies when processing the gst_element_get_state
function. This being the case I'm going to reassign this to gstreamer-
plugins-bad.
