#1771: TopoGeo_addLineString  kills the backend

 Reporter:  strk      |       Owner:  strk         
     Type:  defect    |      Status:  new          
 Priority:  critical  |   Milestone:  PostGIS 2.0.1
Component:  topology  |     Version:  2.0.x        
 Keywords:            |  
----------------------+-----------------------------------------------------
 Again seems related to tolerance (thus ST_Snap):
 {{{
 select createtopology('tt');
 select topogeo_addlinestring('tt', 'LINESTRING(0 1, 2 2, 2 0, 0 1)');
 select topogeo_addlinestring('tt', 'LINESTRING(1 1, 3 2, 3 0, 1 1)', 10);
 }}}

 The above results in a backend crash here ( POSTGIS="2.0.1SVN r9628"
 GEOS="3.4.0dev-CAPI-1.8.0" )
