I got new Macbook Air (M1, 2020) and when I'm trying to use a project
transferred from previous Intel Macbook Pro, I get Segmentation fault 11
in functions that use MultiPoint, MultiLinestring or MultiPolygon.
How to reproduce:
Create a virtualenv, a Django project and start the shell:
{{{
cd /tmp/ && python3 -m venv venv multisegfault && source
multisegfault/bin/activate && pip install django && django-admin
startproject segfaulttest && cd segfaulttest && python manage.py shell
}}}
Copy paste this line to the shell:
{{{
from django.contrib.gis.geos import MultiLineString; MultiLineString()
}}}
You should get **Segmentation fault: 11**.
It may be possible that **GEOSGeom_createCollection_r** causes crash, but
I don't know how to try it outside Django.
Libraries are installed using HomeBrew and they have versions:
Django 3.2rc1 and 3.1.7
$ gdal-config --version
3.2.2
$ geos-config --version
3.9.1
$ python -V
Python 3.9.2
# SELECT PostGIS_full_version();
POSTGIS="3.1.1 aaf4c79" [EXTENSION] PGSQL="130" GEOS="3.9.1-CAPI-1.14.2"
PROJ="7.2.1" LIBXML="2.9.10" LIBJSON="0.15" LIBPROTOBUF="1.3.3"
WAGYU="0.5.0 (Internal)"
Everything is good on Intel Macbook Pro (same library versions) and on
Ubuntu 20.04 (default versions).
