I am currently working with the tifflib under Win32 using VC++ 5.0. When I
read the below message I remembered that I noticed this behaviour too. The
strange thing was that the Tifflib compiled and worked perfectly for a lot
of compression formats including CCITT group 3 and group 4 with the debug
version of the library. When I compiled a release version I got garbage.
When turning optimization off via the the Settings menu the Tifflib worked
fine again.
Probably there is some code in a CODEC that confuses Microsofts optimizer.

'hope that it helps you further...
