PS: It also occures with other nodes like Mix, not sure if something wrong with the Image node.

Can't redo a crash here (tested 2.77a and master (7f57c99be87d6cb1b7ac9f005fa79c374812a8b6))

Please attach images to redo the crash (since its possible the images you're using cause a crash).

Yes. I can't reproduce it with 2.77a official release either, but I do reproduce it with the daily builds. (June 2nd, I think). File uploaded, though I tried many different image sequences, even single image.

Even making both images reference this sequence, I can't redo the bug.
Did you check if this happens on another computer?

Also, its best if you can provide the blend-file and images together in a way we can open and do some steps to re-create the crash.

Since its possible somehow the way I'm referencing the images on load, uses a different image-sequence frame-range or some other detail thats different.
Generally it saves time too, since developers don't have to guess / trial and error to attempt to re-create the error case,

Actually, there are several crash triggers here, all related to backdrop. See this video: https://youtu.be/GWx4XrIQilA
