 Priority:  medium          |   Milestone:  PostGIS 2.0.0

 I've imported a geotiff produced by gdal reading the swisstopo NTv2
 gridshift file.

 After that, this query kills the backend:
 =# create table chenyx06a_longs as select st_centroid(geom), val from (
 select (st_dumpaspolygons(rast, 2)).* from chenyx06a ) as foo;

 Note that dumping band 1 didn't kill the backend.

 Let me know how I can help further debugging the issue.

 The .tif file is attached to this ticket.
