I added a printf("runtime %s compiled %s\n", zlibVersion(), ZLIB_VERSION) in the tif_zip routine and the output when running the program is:

Error from inflateInit (Error -2) runtime 1.2.7 (compiled 1.2.7)

stream.msg = NULL

I also get the error on Linux but there it does not crash. so it seems that using zlib 1.2.7 for libtiff 4.0.3 is not a good idea. When not calling the error function if stream.msg = NULL the output of libtiff looks oke.

I will try 1.2.5 tomorrow.
