Ok, THIS is a good test!!

I can confirm/crash with this one :-(

BUT on 3.10, 3.12 AND current master!!

I also tested on current Windows nightly, there  QGIS does not crash but

QgsGeometry.fromWkt('Polygon ((0 0, 1 1, 1 0, 0
0))').intersection(QgsGeometry.fromWkt('Point (42 0)'))

shows me:

QgsGeometry: PointZ (0 0 nan)

which also is a little strange...?

should this be valid anyway?

I also ran this on Debian in gdb:

(Note that I recompiled all yesterday because bullseye had now python 3.8)

If I run QGIS in gdb (it stops in a thread, but 'continue'-ing for a
couple of times QGIS just starts.
Then copying your python script above in the python console, QGIS
crashes. 'bt' in gdb then shows:

Is this helpfull for any core dev?

Should I create an issue?
