Trouble with AsText(ExteriorRing()) Re: [postgis-users] IsSimple terminating connection

[strk at refractions.net]

No problems with regress test.
Can you provide a testcase for me to check at ?
I would need the smallest possible dataset,
in this case the Geometry which triggers the
segfault when feed to the IsSimple() function.

To find out which one it is I suggest you
define a cursor for select id,IsSimple(the_geom)
and fetch. Last seen id+1 will be the faulting
geometry.

Once isolated create a table as select id,the_geom
where id = <found_id> and produce a shapefile from
it using pgsql2shp. Send the shapefile to me and
I'll see if I can reproduce it.

Thanks.
