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...
