some that we had already fixed locally.
o typeset -f FUNC doesn't print follows command (and expression) substitutions.
o when re-allocating memory, too much may be copied from old memory.
o set -o printed some options sans names.
o emacs mode: <esc>. in very fist command causes core dump.
o pdksh dumps core after a cd command.
o typeset -i reports on array elements that have no value
(at&t ksh reports on array base name - no index).
o ulimit -ctn unlimittttted kills shell (resource exceeded).
o ". /dev/null" says access denied.
o flag field in aliases incorrectly changed (all flags set instead of
clearing ISSET) in exec.c(flushcom).
o ${#array[*]} prints largest index instead of number of (set) elements
in an array (ksh88 does the former).
o sys_siglist[] doesn't always have NSIG non-null entries...
