Crash on startup with SIGSEGV in gr::funcube::fcdpp::make() #1120
Comments
The crash occurs in gr-funcube. I downloaded source and debug symbols to have a look at the crash:
It looks like it crashes the first time it tries to log something, probably because the logger is not initialized. Debian applied a patch which removed logger initialization, and I suspect that's the problem: https://sources.debian.org/patches/gr-funcube/1.0.0-3/update-logging/ |
That's interesting. I really appreciate your looking into this. What is the next stage? Should I try to communicate this to the Debian package maintainers, or is the automated crash report sufficient? |
I sent a short message about the problem to the Debian package maintainer, but have not heard back. It probably wouldn't hurt to file a bug report in Ubuntu's bug tracking system if you have the time. |
I have raised this as you suggest: https://bugs.launchpad.net/ubuntu/+source/gqrx-sdr/+bug/1970126 |
After installing Ubuntu 22.04 LTS and installing gqrx ("gqrx-sdr") from the repositories, gqrx crashes consistently on startup. It worked fine on 21.10. The SDR is a Funcube Pro+. Starting from the console gives:
