(tried to use bugzilla, but kept getting connection errors)

When I create a TIFF file with GeoTIFF excluded from the compilation, the result is valid and runs okay. If however, I link in GeoTiFF, then the program fails with 'Decoding error at scanline 0, incorrect header check'.

I am using libtiff-3.7 from CVS (1 September 2004) and Fedora Core 2 (Reading syms from /usr/lib/libz.so.1.2.1.1).

This same code will create a deflate compressed TIFF file w/ GeoTiFF tags using libgeotiff-1.2.1 and libtiff-3.6.1. (same platform).
