Hi Brad,
Sorry that I missed your mail for so long!
So, I'm pretty certain I've fixed a potential race condition when
accessing the data vector in vector sink lately:
https://github.com/gnuradio/gnuradio/pull/1445
But that should be included in the 3.7.11.1 release you're using... hm.
We should probably be looking into what happens in reset(), right?
Best regards,
Marcus
