artemp/trac2github — Issue #599: segfault in gdal plugin reading large geotiff (for foss4g benchmarking)
Author: artemp
Created: 2011-10-09 20:42:57+00:00
State: open
Labels: GDAL_Input_Driver

The GDAL plugin is segfaulting on line 289 of gdal_featureset.cpp.

It happens on the second render request of the dataset
* first request is a black tile (which is wrong - should be rgb of aerial image)
* second request a segfault right here: http://trac.mapnik.org/browser/trunk/plugins/input/gdal/gdal_featureset.cpp#L289

This is the one of the raster file's details (there are dozens which are all similar):
