#2697: ST_GeomFromGeoJSON() of invalid GeoJSON Polygons crashes server process,
possibly corrupts shared memory

 Reporter:  kochb    |       Owner:  pramsey
     Type:  defect   |      Status:  new    
 Priority:  high     |   Milestone:         
Component:  postgis  |     Version:  2.1.x  
 Keywords:           |  
---------------------+------------------------------------------------------
 When trying to ST_GeomFromGeoJSON certain invalid geojson strings, the
 server process crashes and forces other clients to disconnect.

 Though this is certainly errant geojson, I would expect any error
 generated by a query to not affect unrelated server connections.

 '''To Reproduce'''

 Open two psql connections.  In the first, run the following query:

 {{{
 test=> SELECT
 ST_GeomFromGeoJSON('{"type":"Polygon","coordinates":[1,1]}');
 }}}

 You should receive the following error:

 {{{
 SSL SYSCALL error: EOF detected
 The connection to the server was lost. Attempting reset: Failed.
 !>
 }}}

 In the second, run any query:

 {{{
 test=> \dt
 WARNING:  terminating connection because of crash of another server
 process
 DETAIL:  The postmaster has commanded this server process to roll back the
 current transaction and exit, because another server process exited
 abnormally and possibly corrupted shared memory.
 HINT:  In a moment you should be able to reconnect to the database and
 repeat your command.
 SSL SYSCALL error: EOF detected
 The connection to the server was lost. Attempting reset: Failed.
 !>
 }}}
