[Qgis-developer] QGIS 2.16.1-2 Crashing on Loading GeoTIFFs

[Even Rouault]

Jürgen,

I can reproduce the crash on a fresh new OSGeo4W 32 bit install just GDAL 
2.1.1-1. After a few trial&errors by trying previous versions of gdal, libtiff 
and libgeotiff, I've determined that it is the recent update of libgeotiff 
1.4.2-1 that seems to be the cause of the crashes. When manually reverting to 	
libgeotiff-1.3.0-3 dll, I no longer get the crash on the sample .tif (although 
just substituting the libgeotiff dll is not recommended, as there might be some 
subtle ABI differences in 1.3.0 vs 1.4.2 that might cause later issues)

Interestingly, when installing gdal-dev (2.2.0dev) and sourcing it, I don't 
get the crash, even with libgeotiff 1.4.2-1

I also tried a fresh new OSGeo4W 64 bit install but it fails when downloading 
ogdi.

I'm not sure what is wrong exactly with gdal 2.1.1/libgeotiff 1.4.2 since when 
installing gisinternals binaries ( 
http://download.gisinternals.com/sdk/downloads/release-1600-gdal-2-1-
mapserver-7-0.zip ), gdalinfo works on the provided GeoTIFF. One difference is 
that gisinternal binaries are compiled with the internal version of libgeotiff 
in GDAL, but the sources of that one are sync'ed from latest state of 
libgeotiff SVN, so ~ 1.4.2. One subtelty between internal and external 
libgeotiff regarding GDAL is how some CPL services (the ones parsing CSV files 
mostly) are hooked.
