This bug only occurs when copying tiled BigTIFFs; I generated a stripped version of the same image and it copied without error. The error also occurs when using the -t flag to force tiffcp to convert the stripped image to a tiled image. My test image is 14544x57632, 128x128 tiles, RGB color.
Sorry, I forgot to mention that this is on Windows 10- on Ubuntu it works perfectly fine.
can you tell exactly which compiler was used to build libtiff to exhibit the bug ? 32bits ? 64bits, etc. also which exact version of libtiff sources ? This test is failing : https://gitlab.com/libtiff/libtiff/blob/master/tools/tiffcp.c#L1265 also, could you attach a tiff file that shows the bug ? (if all pixels are same color that shouldnt be too big, with compression)
Bugzilla is no longer used for tracking libtiff issues. Remaining open tickets, such as this one, have been migrated to the libtiff GitLab instance at https://gitlab.com/libtiff/libtiff/issues . The migrated tickets have their summary prefixed with [BZ#XXXX] where XXXX is the initial Bugzilla issue number.
