Does that mean that this issue has been fixed in 4.0.8? The process of upgrading a library version is non-trivial in our workplace and so if this bug has been indeed fixed, I would be happy to move to the latest version.

I am unable to tell you if the problem is fixed. What I can tell you is that active libtiff developers are not usually using Windows for development (although Windows is supported) so it is not getting as much developer testing under Windows as it should. We rely on the larger community to help assure that libtiff is working correctly under Windows.

A large number of bugs and security issues have been fixed since 4.0.0. The fixes we are aware of are mentioned in the change logs, but some issues which were fixed could have unknown side effects.

To look at the change logs, first go to http://www.simplesystems.org/libtiff/v4.0.8.html, and after reading that page, click on v4.0.7, read that page, click on v4.0.6, etc.
