Hello,

Some more information.

When I setup my Core 2 Duo system I got GNURadio code from the main
trunk.  The laptop was using an older version of the main trunk and did
not have a problem.  A couple of days ago I updated the laptop from the
current main trunk and now I get the same problem with fft.  I also find
problems with oscilloscope on both systems if I select certain timebase
entries.

I suspect a recent change caused this and likely the example code needs
to be updated.  I may look at it over the next few days in my hotel room
to kill time.
