The situation is no better with jpeg 8 either (trasncode 1.1.5)
Core was generated by `transcode --progress_meter 1 --progress_rate 10 --write_pid /tmp/todisc-work.0/'.
Program terminated with signal 11, Segmentation fault.

explicitly set do_fancy_downsampling to FALSE
Apparently, when settings dinfo.raw_data_in,
previous version jpeg automatically set dinfo.do_fancy_downsampling to
FALSE. Newer versions (since 7) of media-libs/jpeg do not do that anymore and
the program must do it explicitly (although I have not found any documentation
to that effect).
Compile tested only, but a similar fix in mjpegtools (but output rather than input) works.
