Hi Vasil & Phillipp, I just un- and reinstalled gnuradio from source (basically following the steps at the wiki)... that did not solve the problem.
Im on version 3.10.4.0 and im on Ubuntu 20.04. @Phillipp you were right, gnuradio does not crash if I open another flowgraph. The import I was originally aiming to do works now. And i found when gnuradio segfaults: it happens when I add a variable block with "mymodule.phy_header().formatter()" (maybe that additional info is useful) @Vasil I did install the debug symbols, but when I do the command, it still shows Reading symbols from python... (No debugging symbols found in python) And the rest of the output is still the same...so I dont know what wrong here. That indicates that the installation of the debug symbols went wrong? Thank you very much for your help so far, I would be very thankful for any further help 😊 Best, N ________________________________ Von: Vasil Velichkov <vvvelich...@gmail.com> Gesendet: Dienstag, 21.

The _impl.{h,cc} files as the .h file most likely does not contain anything that's important for this crash. > I could provide anything that "helps to help" . Install the gnuradio's debug symbols and then take another backtrace. How did you install gnuradio, which version and which Linux distribution?
