I *think* it's probably a bug, try changing the line in mac_label.c from:
mpm[mpc].start = session_start + hce->hfs_map_size / HFS_BLK_CONV;
to:
mpm[mpc].start = hce->hfs_map_size / HFS_BLK_CONV;
and recompile.
Then use the -part option to mkisofs when creating the second data session.
It looks like using an HFS volume as the data part of a CD+ requires a
partition table, but the address of the volume in the partition table is
relative to the session start, not the CD start (as I had assumed)
I guess you must be the first person to try and do this as the code's been
like this since November 1999 ...
Let me know if this works ...
