#3329: Topology population regression
----------------------+---------------------------
 Reporter:  strk      |      Owner:  strk
     Type:  defect    |     Status:  new
 Priority:  blocker   |  Milestone:  PostGIS 2.2.1
Component:  topology  |    Version:  2.2.x
 Keywords:            |
----------------------+---------------------------
 Another regression spotted between plpgsql and C version of topology
 loading.
 I'm attaching the smallest input found so far, can probably be further
 reduced. Thanks @esseffe for finding this out.

 To reproduce the error:
 {{{
 strk=# select createtopology('rer_exception');
  createtopology
 ----------------
            2650
 (1 row)


 strk=# select topogeo_addpolygon('rer_exception', st_geometryn(geom, 1))
 from rer_exception order by gid;
 ERROR:  SQL/MM Spatial exception - geometry crosses edge 58
 }}}

 Switching to the plpgsql version works and returns 60 faces (with a few
 duplicates and a null, which isn't really expected):
 {{{
 ALTER EXTENSION
 strk=# select topogeo_addpolygon('rer_exception', st_geometryn(geom, 1))
 from rer_exception order by gid;
  topogeo_addpolygon
