Debugging finished!

Result: I guess there is some wrong header-file mixup with libjpeg-80 at
gentoo:

Autorotation terminates premature with error (but does not print an error
message, see bug #276154):


The error is recognized and autorotation is terminated:
>  info->crop_yoffset >= info->output_height
>   (= 3067336080)         (= 2352)

the reason for this:
 "info->crop_yoffset_set" should be "JCROP_UNSET", but is set to: 
>   crop_yoffset_set	Digikam::<anonymous enum>	134814873

the reason for this:
 the second parameter to "jtransform_request_workspace(...)" at line 500 is
already "defect"


the reason for this:
 "jpeg_transform_info transformoption" initializes wrong with:
