Hi Tom,

The commit that caused the issue was 2bb2b31.  I did a cmake, make, make install after checking out that commit.

I will go back, clean out the build folder, checkout 2bb2b31 and try again.

Ok, thanks. It's possibly due to the change in commit b4bbda76 that adjusted how one of the classes in ControlPort was defined. That should just take clearing things out and rebuilding to fix. As I said, it's working fine for me now even though I saw a similar problem.

I went back to build b5006c1 , rebuilt, and gnuradio-companion is running again...

~gnuradio$ git checkout b5006c1

System is Ubuntu 13.10, Ice3.5

Did you try rebuilding before doing this? What was the original commit that was giving your trouble so we could see what's changed since b5006c1 that could be causing this. Frankly, that shouldn't have anything to do with anything.

Built 3.7.5git, and updated UHD to latest. Builds fine. Gnuradio from the command line runs fine.
When trying to run gnuradio-companion it core dumps:

Any advice?

Well, shoot. I was really hoping that was just me and something weird I had done to my system. I had a similar issue. I just removed my installed version of GR, deleted all my build files, and rebuilt. If it's still causing you issue, you can try turning off ControlPort with -DENABLE_GR_CTRLPORT=False in the cmake command.

I'm not sure what it is because this only happened on one of my machines. Potentially some weird interaction with Ice during the rebuild.
