Hi all,
I've been getting an intermittent core dump when my gnuradio script closes. It doesn't seem to be a very critical error, but I ran across this:
https://lists.gnu.org/archive/html/commit-gnuradio/2015-04/msg00327.html
Which shows a bt different from the one I'm getting, and says to report if that's the case.
My program is not using controlport, and I'm not passing THRIFT as a build requirement:
