Hello,

When I try to use TIFFFdOpen on Windows 10 64bit - but it crash. In

attachment there is my testing code. I found this problem when I was

testing poppler[1] utility pdftoppm (to convert pdf to tif).

IMO this is relevant to Bug 1941 - Win64 problem with tif_win32.c's

TIFFOpen() use of HANDLE (w/patch)[3],

Unfortunately " Bugzilla has suffered an internal error", so new account can not be created e.g. I can not comment it there too.

Does anybody has the same experience or is there workaround for this?

I use the latest code[4] build with cmake and clang (version 9.0.0 (trunk) Target: x86_64-pc-windows-msvc).
