[geos-devel] Bug on offset calculation on recent GEOS versions

Hi list,

Apologies for bringing up a bug report on the mailing list, but I'd
love to get some more feedback on a rather scary regression I've found
on recent GEOS versions (https://github.com/libgeos/geos/issues/477)

In a nutshell, certain simple single-part linestrings magically become
multi-part linestrings with gaps in them after offsetting the curves.

Is there anyone interested in fixing this? If so, can you please send
me an estimate of the cost of this fix?
