 I got the same symptom and am investigating it.  Can you rebuild the
 binary with a debug option like this:

 % cd /usr/src/usr.sbin/makefs
 % make clean
 % make DEBUG_FLAGS=-g
 % make DEBUG_FLAGS=-g install

 and then send me the output of the following command?

 % printf "run -t cd9660 -o chrp-boot -o rockridge -o label=pseries -B4321 p.iso /data1/netboot/powerpc64/\nbt\nf 1\n f 2\n" | gdb -x /dev/stdin -batch /usr/sbin/makefs

 In my environment both the old and the new version could reproduce
 it.  I am not sure if mine is the same as yours at this moment,
 though.
