[RASTER] ST_DumpAsPolygon crashes the backend

[strk]

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.

Oh, it is a single band. May be the cause for the crash…
