[gdal-dev] gdal 1.10.0 1.9.2 segmentation faults for WCS requests

[Ulrich Leopold]

Dear list,

when using gdal version 1.10.0 and 1.9.2 on ubuntu 12.04 and ubuntu 
13.04 we get a segmentation fault for any WCS requests (see below for an 
example). Using wget the request works and we can save the image. 
gdalinfo on the saved image works correctly, just not on the request 
directly.

Any idea why the segmentation fault when using the WCS request directly?


Best, Ulrich
