Sadly I don't have a coredump nor a test to reproduce it yet, but after looking at the usages of `GEOSisEmpty` it looks like https://github.com/postgis/postgis/blob/80cfa0b0c050499518138a4a972a4033f2b347b7/liblwgeom/lwgeom_geos_clean.c#L701 could be the culprit, as it's passing the result of a function that might be NULL to `GEOSisEmpty`. I'll see if I can reproduce it somehow locally.",defect,closed,medium,PostGIS 2.4.7,postgis,2.4.x,fixed,,
