Description

After I put in NaN coordinate tests in garden tester, the berries are crashing on this:

	SELECT ST_Split('LINESTRING Z (1 2 NaN,3 4 10,5 6 NaN)'::geometry
					,'MULTIPOINT(EMPTY,2 1,2 4, 4 5)'::geometry )

On windows testing with

POSTGIS="3.5.0dev 3.4.0rc1-819-ge433f1884" [EXTENSION] PGSQL="150" GEOS="3.12.2dev-CAPI-1.18.2" (compiled against GEOS 3.13.0) PROJ="8.2.1 NETWORK_ENABLED=OFF 

PostgreSQL 15.0 on x86_64-w64-mingw32, compiled by gcc.exe (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0, 64-bit

it doesn't crash but gives

ERROR:  invalid memory alloc request size 1073741824
