Regressión of conversion from TIFF to JPG

[vtamara]

Problem converting TIFF to JPG with convert 6.9.10-36 on OpenBSD/adJ. It doesnt' happen with convert version 6.9.10-10.

I uploaded an example of an image that shows the problem:
https://github.com/vtamara/prob-image-m ... F?raw=true

If I run with 6.9.10-36 it shows:

And it doesn't produce /tmp/a.jpg

Your image fails to convert for me on IM 6.9.10.36, IM 6.9.10.64 and IM 7.0.8.64 (and other IM 6 versions) Q16 Mac OSX Sierra.


I get

Code: Select all

convert -quiet 101872_127179.TIF 101872_127179.JPG

But it does convert with 6.9.10.14 Q16 Mac OSX even with similar errors other than the last error above.

It also can be opened with Mac Preview.
