[mapserver-dev] Python mapscript segfault on OSX

[Seth G]

Hi all,

For info - looks like Even setup OSX CI on GitHub actions for GDAL - https://github.com/OSGeo/gdal/pull/2646
https://github.com/OSGeo/gdal/blob/master/.github/workflows/macos.yml

https://github.com/Homebrew/homebrew-core/blob/master/Formula/mapserver.rb builds on Python 3.8 - I guess things work differently on Macs than Windows which is stuck with https://github.com/mapserver/mapserver/issues/6101
