I've never used it myself, because I don't have a use for it, but from what I read, it might be able to detect at least some error cases. Maybe it's worth trying. Do you think that would lead to a crash every time?

Alas, this doesn't seem to work on my M1 Mac, but maybe it does on your x86_64 system.

I've seen to open errors in your log. Are you saying that these happen because you started Emacs from src this time? FWIW, I don't see differences when starting one or the other. > On Aug 20, 2022, at 2:34 AM, Gerd Möllmann wrote: > > Could it be that one or more jpegs of yours is invalid in some way? > Maybe you could check this with the 'jpeginfo' utitlity.
