Subject: crash with CCITT4 and large files
Content-Type: text/plain; charset=us-ascii

Sender: owner-tiff@olympiakos.com

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
