[QGIS-Developer] QGIS unstable on debian testing

Thanks Bas,
I completely removed libproj19 and its dependents and built from source the
following chain:
-proj 6.3.1
-libgeotiff master
-libspatialite 4.3.0a (with
CFLAGS="-DACCEPT_USE_OF_DEPRECATED_PROJ_API_H=1")
-gdal master
-qgis (a few days old master)

Unfortunately, things have not changed for the better.
Instead of the freezes I now get normal crashes and stability has not
improved. I also got a new stack trace I hadn't seen before downgrading:

Is anyone using qgis on Debian testing without issues? What else could I
try?

Thanks
