[QGIS-Developer] QGIS unstable on debian testing

[Richard Duivenvoorde]

Hi uclaros,

I'm on master/bulseye too, and I do not encounter frequent crashes.
Is it possible that one of your plugins is creating havoc? Also because
it is with all you versions on the same machine (sharing your profile)

Maybe create a fresh profile with no plugins in it?

You are compiling against distro proj and gdal, yes?

If you encounter still crashes, you can compile 'with debug', and using
gdb maybe can debug the crash?

Regards,

Richard Duivenvoorde
