[gdal-dev] gdal_merge and BIGTIFF option fails

[WolfgangZ]

Hi,
I'm trying to merge some tiles into a single tiff file that will be 
bigger than 4 GB. But when it reaches the 4GB the following error occurs:
FIFFWriteEncodedTile() failed
TIFFAppendToStrip: Maximum TIFF file size exeeded.

I have also to report that in the very beginning I get following error:
TIFFFetchStripThing: Sanity check on size of "TileOffsets" value failed.

I'm using WFTools 2.0.4 on Ubuntu

Any suggestions
Wolfgang
