No, run it on an x86 and you'll get 'char is signed'. I was hoping your
arm toolchain was somehow different from mine.

Perhaps my test case was too brief. Could you try:

mkdir /home/ubuntu/.ecryptfs
mkdir /home/ubuntu/a /home/ubuntu/b
cat > /home/ubuntu/.ecryptfs/ab.conf << EOF
/home/ubuntu/a /home/ubuntu/b ecryptfs none 0 0
EOF
ecryptfs-wrap-passphrase /home/ubuntu/ab.sig
(type 'x\n' twice)

then to try the mounting:

ecryptfs-add-passphrase
 (type 'x\n')
mount.ecryptfs_private ab
