AlphaShape crash in PostGIS garden tests - with invalid geometry input

Not sure if this is an issue in PostGIS or SFCGAL. I have ticketed in PostGIS here - POSTGIS="3.3.0dev 3.2.0-792-g78308862c" [EXTENSION] PGSQL="110" GEOS="3.11.0dev-CAPI-1.16.0" SFCGAL="SFCGAL 1.4.1, CGAL 5.3, BOOST 1.78.0" PROJ="7.2.1" GDAL="GDAL 3.4.2, released 2022/03/08" LIBXML="2.9.9" LIBJSON="0.12" LIBPROTOBUF="1.2.1" WAGYU="0.5.0 (Internal)" RASTER PostgreSQL 11.2 on x86_64-pc-mingw64, compiled by gcc.exe (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0, 64-bit
