I had this problem a couple weeks ago. After deleting the build  
subdirectory and rebuilding it went away until today  
when it came back. I deleted the build directory and  
re-cmake/make/install/ldconfig, but the problem will not clear.

These can be a bit annoying. You can inspect the core dump  
([http://gnuradio.org/redmine/projects/gnuradio/wiki/TutorialsDebugging](http://gnuradio.org/redmine/projects/gnuradio/wiki/TutorialsDebugging))  
to see where this happens. Chances are you rebuilt GNU Radio and this is  
some OOT module that is acting up.
