#1029: geometric object crashes server with Out Of Memory
---------------------+------------------------------------------------------
Reporter: cousinm | Owner: pramsey

Component: postgis | Version: 1.5.X

Comment(by pramsey):
From Martin:
This geometry causes problems in JTS as well (all versions). The problem
is that there is an area of the geometry where there are about 2000
circular polygons (totalling about 71000 pts) which are all *almost*
identical. This causes the noding algorithm to have a hissy fit.
It should be possible to get validation working at least, since the
geometry is obviously invalid (due to the numerous overlaps).
Also, Unary Union works fine, with respectable performance. So if it's
necessary to reduce the polygon to something workable, that's the way to
do it.
