Hello all,

we tried to use the Tifflib for decoding large images with CCITT4 coding which have more than 65535 pixels/line. The only effect is, that the programm crashes. Images with fewer than 2^16 Pixels/line work fine. Is this a known bug?

We also see sporadic crashes while decoding smaller images (which are although about 40-100MB in size). It's everytime a access violation in the subroutine

tdata_t _TIFFrealloc(tdata_t p, tsize_t s)

in the file tif_win32.c.

All our files are black and white and use packbits, lzw or ccitt4.

best regards
Bernd Stahlbock
