environment-modules (3.2.10-8) breaks with bash 4.3.11(1)-release

[Predrag Micakovic]

environment-modules (3.2.10-8) fails to execute batch (atd) jobs under bash 4.3.11(1)-release. This is likely caused by changes in bash functions in follow-up to shellshock fixes to bash.

Test with environment-modules (3.2.10-8) uninstalled and this sample script:

cat /tmp/ls.sh

#!/bin/bash
ls > out.ls

Schedule with 'batch < /tmp/ls.sh' and you will receive the correct output.

Now install environment-modules and try the same. You will receive an error along these lines:

sh: 46: BASH_FUNC_module%%=() { eval `/usr/bin/modulecmd bash $*`
}: not found
sh: 46: export: BASH_FUNC_module%%: bad variable name

Admittedly, this has to be fixed upstream, but we do have a broken package as it stands.

Tested on Ubuntu 14.04.1 LTS (GNU/Linux 3.13.0-43-generic x86_64).
