Adding a controller before adding any ports causes an assertion in LOCI

[dtalayco]

I’m having an issue with adding a controller before I’ve added any ports.

When doing this, I get some packets from the controller that eventually cause the next assertion (in the LOCI module):

Of_object.c:95

ASSERT(obj->track_info.magic == OF_OBJECT_TRACKING_MAGIC &&
"of_object double free?");

1.   Adding a controller with no ports – works well.
   

2.   Adding a ports, then adding a controller – works well.
   

3.   Adding the controller, then immediately adding ports – results in a packet with an empty buffer & assertion.
   

4.   Adding the controller, sleeping for a few more seconds, then adding ports – works well.

Here is the log output:
