I am using the ksh included with OpenBSD (which reports a very old
version number but is maintained/developed in OpenBSD):

$ sysctl kern.version
kern.version=OpenBSD 6.0-beta (GENERIC.MP) #2058: Mon May 16 22:38:41 MDT 2016
    address@hidden:/usr/src/sys/arch/amd64/compile/GENERIC.MP

$ echo $KSH_VERSION
@(#)PD KSH v5.2.14 99/07/13.2

Commenting out "set -e" and it works :-)

Is there a specific way to provide further debug output that helps
investigating this issue?
