The changes for #741 have been merged in the 3.5 branch upstream, and included as in patch in geos (3.5.1-4). The updated package will be available in unstable in a few hours. I don't think the issue is severe enough to warrant a stable-update, so the fix is unlikely to find its way into stretch. If you need it there, you should either cherry-pick the change from 3.5.1-4 or backport the whole package yourself. > [0] https://lists.debian.org/debian-gis/2016/10/msg00036.html > [1] https://lists.debian.org/debian-gis/2017/08/msg00008.html Kind Regards, Bas -- GPG Key ID: 4096R/6750F10AE88D4AF1 Fingerprint: 8182 DE41 7056 408D 6146 50D1 6750 F10A E88D 4AF1
