looks like you’ve found a bug! Here’s how I debugged this (it’s a good
and easy learning example):

  • Build GNU Radio w/ debug symbols
  • On my system, I need to allow core dumps: Run ulimit -c unlimited
  • Then run the app, it’ll produce a file called core
  • Open that with gdb: gdb /usr/bin/python core
  • In the gdb command line, run bt

It’ll show you it crashed on line 186. As you can see, the code makes
the assumption that d_pilot_carriers is populated, which it isn’t –
there’s your bug!

Do you want to submit a fix?
