This is pretty consistent in Linux but not in MAC and Windows. Is this a known issue? How to resolve this? Our libTIFF version is 4.1.0.
I suggest using valgrind and/or ASAN to see if any harm was done prior to the close. Valgrind is good at finding heap related errors and does not require a special build configuration beyond some level of debug symbols. ASAN is capable of a bit more (and it is a lot faster) but it requires that the code be compiled with special options (and the compiler needs to support ASAN).
These interfaces do work well in other software.
