Hi,
I am running MapServer version 6.5-dev on Windows and I suppose it has the
support for kerneldensity layers. Could someone show the LAYER part that works
with the Natural Earth populated places dataset
http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/cultural/ne_10m_populated_places.zip?
I have created .qix index but not touched the data in other ways.
I have indeed managed to get some coloured stripes out at some scales but what
I mostly get is Internal server error (http 500). MS_ERRORFILE does not show
any errors and Apache error log is probably recording just this:
[Sat Sep 27 21:57:27 2014] [error] [client 127.0.0.1] Premature end of script

My current LAYER (or layers, one for data and one for kerneldensity):

What I have tried so far has been to comment out this and that but result seems
to be always the same.

Hi Jukka,
The good news/bad news is that I can reproduce this same issue on
Windows, with MapServer-master and GDAL (both trunk and 1.11.1 release).
I have built both MapServer and GDAL in debug mode, and have placed
the debug messages (and test case) in a ticket at
https://github.com/mapserver/mapserver/issues/5019 It seems to crash on
a memcpy call by GDAL, hmmm...
