David, the following test case crashes ksh (with and without your patches):
======================
(
print '('
integer i
for ((i=0 ; i < 16384 ; i++ )) ; do
printf '\tinteger var%i=%i\n' i i
done
printf 'typeset -a ar=(\n'
for ((i=0 ; i < 16384 ; i++ )) ; do
printf '\t[%d]=%d\n' i i
done
print ')'
print ')'
) | read -C hugecpv
set -o xtrace
compound hugecpv2=hugecpv
compound hugecpv.snapshot=hugecpv2
unset hugecpv2
compound hugecpv2=hugecpv
print -v hugecpv2 | wc -l
======================
gdb reports this stack trace:
