Roger,

   I'll include more information the next time I have an issue.

   This might well be the issue. geos was upgraded from the summer's 3.6.3 to
the very recent 3.7.0 and when I run weekly upgrades to installed
Slackbuilds.org packages that was upgraded. I'll rebuild gdal and check that
the issue is resolved.

   Not long ago I did rebuild the sequence proj -> geos -> gdal -> grass and
the R upgrade might have missed that.

Many thanks,

Rich
