Confirm support for GDAL 3.2 and GEOS 3.9.

[Sebastian Kapunkt]

Using MultiPolygon on Apple MacBook pro with the M1 chip causes segmentation fault.

Here is what I did to produce the error:

python manage.py shell

>>>from django.contrib.gis.geos import MultiPolygon
>>>MultiPolygon()
[1] 34350 segmentation fault  python manage.py shell

I have these relevant settings in my settings.py:

GDAL_LIBRARY_PATH = os.getenv("GDAL_LIBRARY_PATH")
GEOS_LIBRARY_PATH = os.getenv("GEOS_LIBRARY_PATH")

.env

export GDAL_LIBRARY_PATH=/opt/homebrew/lib/libgdal.dylib
export GEOS_LIBRARY_PATH=/opt/homebrew/lib/libgeos_c.dylib

GDAL 3.2 and GEOS 3.9 are not supported by Django, see ​docs. I've change this ticket to a new feature.

I guess this is not related to GEOS or GDAL versions, but M1 CPU architecture and the bug is in GEOS. See #32600.

I've in this Macbook Pro (13-inch, 2017, Intel Core i5) software listed below and I've no problems with multi geometries.

$ python manage.py shell

My new Macbook Air (M1, 2020) throws Segmentation fault 11 (as seen in #32600).

$ geos-config --version

Aapo, thanks for details. Even if the crash is not related to GEOS or GDAL versions, this ticket is still valid as we have some tests failures with these versions.
