gdal_translate malloc error

[drunix]

Trying to create a WMS service XML file to use in QGIS. Running the Kyngesbury port on a Mac (10.9.2)

gdal_translate "​http://mangrove.cnr.berkeley.edu/arcgis/rest/services/SONOMA_HYDROFLATTENED_BARE_EARTH_HILLSHADE/ImageServer?f=json&pretty=true" s.xml -of WMS gdal_translate(9848,0x7fff7b4d3310) malloc: * error for object 0x10241f730: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug Abort trap: 6

gdal_translate --version GDAL 1.10.1, released 2013/08/26

Could you attach your XML file and the exact gdal_translate command you used? Have you read ​http://www.gdal.org/frmt_wms.html and followed the syntax used in the examples?

William, I think you should disable libdap in your builds. DODS is really a niche driver and libdap seems to be not very robust...

Replying to jratike80

The exact syntax I used is in the initial report. I did not attach an XML file, because there is none; apparently the command crashes before it generates output. Once more

gdal_translate " ​http://mangrove.cnr.berkeley.edu/arcgis/rest/services/SONOMA_HYDROFLATTENED_BARE_EARTH_HILLSHADE/ImageServer?f=json&pretty=true" s.xml -of WMS

Thanks for the reference to the docs, will look at that.

I can't test this case because for some reason the ArcGIS REST requests do not work for me as described in the GDAL WMS driver page. For example this one:

gdalinfo "http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer?f=json&pretty=true"

ERROR 4: `/tmp/file.dat' not recognised as a supported file format.
gdalinfo failed - unable to open 'http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer?f=json&pretty=true'.

This happens with Win-7 and GDAL 1.11dev, released 2013/04/13 from gisinternals. I may have something wrong with the directory for temporary files. Normal WMS service works OK for me as

gdalinfo "WMS:http://server.com/....

Likely a libdap issue and/or packaging. Closing
