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.
It is actually r230354, this is the commit which shows the failure.
And I reverted back to 230353 and onfirmed that it 'works'.
I additionally built with -O0 -g, see below.
If you need more details, I'll be out the next 15h but later on I can
continue.
Thank you very much!
Andreas
