Using the above and one of the UDF images that I am about to email you a URL to,
and the above, the process exits normally (w/o hitting breakpoints) and w/o
printing the RR error.
But digging into this a little, it seems to be an argument order issue.
works: -read_fs norock -indev ...
problems: -indev ... -read_fs norock
So running GDB but flipping the argument order from your example:
(gdb) r -indev /media/scratch/DVDrs/ballards_world.iso -read_fs norock
Starting program: /home/jon/git/xorriso-1.4.7/xorriso/xorriso -indev /media/scratch/DVDrs/ballards_world.iso -read_fs norock
