How to install debug symbols largely depends on how you installed gnuradio and the distribution that you are using. For Ubuntu you can get some info here https://wiki.ubuntu.com/Debug%20Symbol%20Packages Also it looks like the crash is in gnuradio's digital. Can you share the part of source code where you are using it? Regards, Vasil
