           Summary: GstBaseTransform can cause ivalid memory references

          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: gstreamer (core)
        AssignedTo: gstreamer-bugs at lists.sourceforge.net

When the following conditions are met:
* (part) of the pipeline is in pull mode
* there are at least two elements based on GstBaseTransform there
* at least the first of those elements is in pass-through mode
gst_base_transform_handle_buffer will eventually try to unref an unallocated
buffer.

This is a regression since 0.10.18.

Examples attached.
