This is caused by bad description of chroot in the callTable. See:
[EMAIL PROTECTED]:/usr/src/ltp-git$ grep chroot \
testcases/ballista/ballista/callTable*
testcases/ballista/ballista/callTable.all:unistd.h function int
chroot b_ptr_buf
The b_ptr_buf is causing problems. Given that chroot accepts directory names,
it should be replaced with b_fname. See the contents of templates/ directory
for the list of datatypes possible.
