Unfortunately, recent zlib releases are not ABI compatible with older ones (even though it claims to be) and the operating system often delivers an older version. When I installed the latest version, it caused problems for me under Solaris, so I uninstalled it and continued using the system-provided zlib version.
I used 1.2.7 when building the Solaris/Linux version. With ldd I also see a dynamic version of the system so there might be something wrong with that.
It is a common problem to build with one library and then find out that a different one is being used at run-time. If ldd shows that the system version is used rather than the one you built libtiff with, then that would be a problem.
I doubt that libtiff has seen a lot of testing with zlib 1.2.7 because most developers use the version provided with the system.
