gdal_sieve.py segfaulting in GDALSieveFilter

[flewellyn]

Running the gdal_sieve.py program distributed with GDAL/OGR (version 2.0.0, compiled from source, x86_64 using GCC 4.8.4 on Ubuntu 14.04) with the attached raster as the input file, I get a segfault.

To avoid cluttering this ticket's text, I have placed a GDB backtrace at this pastebin location:

Here is the command line I used to run the program:

gdb -ex r --args python /usr/local/bin/gdal_sieve.py -q -st 1500 dissolvetest.tif dissolveout.tif

I have attached the file "dissolvetest.tif" to this ticket.

I think the issue is resolved in trunk. Probably fixed by r30151

gdb -ex r --args python /usr/local/bin/gdal_sieve.py -q -st 1500 dissolvetest.tif dissolveout.tif

Exactly. I confirm this is a duplicate of ​https://trac.osgeo.org/gdal/ticket/6096 due to the presence of nodata value. Fixed by GDAL 2.0.1
