2015.04.02 20:22 "[Tiff] problem reading directories past 2GB on a 64bits system", by Romain Franconville

I'm using libtiff 4.0-3 on Ubuntu (64bits) 14.04.

I'm trying to read tiff files that are signed 16bits. Everything run smoothly for files smaller than 2Gb. But I cannot access directories past that limit.

TIFFSetDirectory returns the following error in those cases:

     TIFFFetchDirectory: Sanity check on directory count failed, zero tag
directories not supported.
     TIFFReadDirectory: Failed to read directory at offset 256.

Opening as bigtiff doesn't make a difference (expected since it's still less than 4Gb).

Any ideas of what might be going on?

Thanks,
Romain
