1. The bug does not occur when /bin/ksh is started with the -x option.
2. The bug does not occur when the
if test -z "$show_help"; then
part is replaced with a
case "$show_help" in "")
3. When I remove some parts of the large show_help block, the
segmentation fault occurs after some commands have been invoked.
Since this behavior is hard to describe and explain correctly, I suggest
that we discourage the use of /bin/ksh on Solaris altogether.
