[geos-devel] Bug in GEOS not in JTS

the following snip (for PostGIS) always causes a SIGABRT. I am sure
that it is in GEOS.
select buffer(shape,0) from
select 'MULTIPOLYGON(((2170000 1350000,
2170000 1350176.60928587,2170055.96366235 1350000,2170000 1350000)))'::
geometry as shape ) as a
actually any shape that is the left 1/2 of a north up oriented
rectangle seems to cause the SIGABRT. the error can be triggered by
buffer(), difference(), intersection(), and symdifference().
buffer(shape,0.00001) does not SIGABRT in the above example.
I tested this and several similar shapes that bomb in PostGIS and they
validate correct in JTS/JUMP. Even the buffer(0) fcn works in JUMP.
does anyone have a working version of doc/example.cpp against CVS
that I can use to track this down?
