[geos-devel] Buffering Multipolygons

Hi All: I'm wondering if someone can confirm that buffering a
multipolygon works with GEOS 2.1.1. I'm testing my conversion code and
am having problems with just this case: simple polgons with/without
holes work fine, anything with multiple outer rings does not (bus error
on Mac OS). The conversion code must be close because computing a convex
hull on the same test shape works fine.

I've attached a small graphic that shows the multipolygon (with GEOS
computed convext hull)...
