I don't think you'll find an APAR for this. The change was intentional.
The korn shell was modified in 5L to be posix compliant. This compliance
requires that all numeric expressions begining with a leading zero be
interpreted as an octal number.
I think I saw this somewhere in the AIX v4.3 to 5L Migration Guide...
