Error while optimizing JPG file

[1024mb]

Just got multiple errors with this same message, all the files are JPG, unfortunately I can't share the files:

Exception happened when optimizing or comparing the image:

Hmm I'll look into it, would you be able to share one of the files privately?

I have been testing some of my public files and I just got the same error message with one, here it is (zipped just in case):
1399751938250.zip

Btw, I have been getting some Optimized image isn't equal to source image. and I have ticked the save failed files, do those files not constitute as failed?

Apparently it's an issue with the EXIF comparison tool I'm using, I've created an issue in his Github:
oozcitak/exiflibrary#111

What save failed files does is store the failed file as {filename}_Failed.jpg. This makes investigating what went wrong a bit easier. It won't ever overwrite the destination file though of the optimization failed.

Thanks, hopefully this gets fixed though it has only happened with some files.

Oh, right, I just realized I forgot to add something to my previous comment. I meant that when I get those errors and "save failed files" is enabled the (failed) files aren't saved, I got no {filename}_Failed.jpg, that's why I was asking that.

Can you guys maybe post in the GitHub issue I've mentioned? Maybe the owner of the library I'm using for the exif data can try to fix it.

I've got the same error using directly the ExifLib library - added a comment to your post @devedse
