It was originally discovered by people using some version of FreeBSD's
/bin/sh.  I was able to reproduce it using the version of ash in
Debian unstable.

/tmp $ cat > test.sh
case foo in
esac
/tmp $ sh test.sh
test.sh: 3: Syntax error: end of file unexpected (expecting ")")
/tmp $ ls -l /bin/sh
lrwxrwxrwx    1 root     root            3 Mar  8  2001 /bin/sh -> ash
/tmp $ dpkg -l ash | tail -1
ii  ash            0.3.8-35       NetBSD /bin/sh
