Created an attachment (id=738) [details] stacktrace On 4.0.7, with the undefined behavior sanitizer (-fsanitize=undefined): tiffcp -i $FILE /tmp/foo runtime error: null pointer passed as argument 2, which is declared to never be null Testcase: https://github.com/asarubbo/poc/blob/master/00122-libtiff-nullptr-tif_unix FTR: it is confirmed on master
I hit an assertion in TIFFWriteDirectoryTagCheckedRational(), which is now fixed per //bugzilla.maptools.org/show_bug.cgi?id=2535 With HEAD, I do not get the error you got : {{{ TIFFReadDirectoryCheckOrder: Warning, Invalid TIFF directory; tags are not sorted in ascending order. 00122-libtiff-nullptr-tif_unix: Warning, Nonstandard tile length 3, convert file. TIFFReadDirectory: Warning, Unknown field with tag 45489 (0xb1b1) encountered. TIFFReadDirectory: Warning, Unknown field with tag 40448 (0x9e00) encountered.

With Head, I still get the failure: /tmp/portage/media-libs/tiff-9999/work/tiff-9999/libtiff/tif_unix.c:348:12: runtime error: null pointer passed as argument 2, which is declared to never be null
