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
}}}

Comment:
GDAL 3.2 and GEOS 3.9 are not supported by Django, see
[https://docs.djangoproject.com/en/dev/ref/contrib/gis/install/geolibs/
docs]. I've change this ticket to a new feature.

Comment (by Aapo Rista):
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.

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

Comment (by Mariusz Felisiak):
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.
