Hello,
I found out that exiftran segfaults when passed the option '-g'.
I found it out, since geeqie invokes exiftran with that option (as well
as others).


The bug seems to be reproducible with all my JPEG photos, see for instance
the attached one (which is just a sample photo, please do not care about
its poor quality...).

  $ exiftran -9 -o test.jpg -g dscn4348.jpg
  Segmentation fault
  $ echo $?
  139
  $ ls *.jpg
  dscn4348.jpg

No rotated image is created, since the program segfaults.


If I instead drop the '-g' option:

  $ exiftran -9 -o test.jpg dscn4348.jpg
  $ echo $?
  0
  $ ls *.jpg
  dscn4348.jpg  test.jpg

And file 'test.jpg' is rotated version of 'dscn4348.jpg', as it
should be.


Please investigate this bug and/or forward my bug report upstream,
as appropriate.

Thanks for your time!
Bye.

I confirm the crash on any jpeg file with -g option. The crash occurs in
libjpeg62-turbo as the backtrace shows:
