Why do I get error messages after patching BASH for the Shellshock vulnerability?

Symptom:

ash: BASH_FUNC_module(): line 0: syntax error near unexpected token `)' bash: 
BASH_FUNC_module(): line 0: `
BASH_FUNC_module() () {  eval `/cm/local/apps/environment-modules/3.2.6//Modules/$MODULE_VERSION/bin/modulecmd bash $*`' bash: error importing function definition for `
BASH_FUNC_module' bash: 
BASH_FUNC_module(): line 0: syntax error near unexpected token `)' bash: BASH_FUNC_module(): line 0: `BASH_FUNC_module() () {  eval `/cm/local/apps/environment-modules/3.2.6//Modules/$MODULE_VERSION/bin/modulecmd bash $*`' bash: error importing function definition for `

BASH_FUNC_module() () {  eval `/cm/local/apps/environment-modules/3.2.6//Modules/$MODULE_VERSION/bin/modulecmd bash $*`'

The patching of BASH due to the shellshock vulnerability has introduced some changes with respect to the function definition syntax in exported functions

If you defined and export a function:
$ myfunction () { echo "hello world"; } $ export -f myfunction

the corresponding environment variable is now different.

The old form:
myfunction=() { echo "hello world"}

The new form:
BASH_FUNC_myfunction()=() { echo "hello world"}
The two forms are not compatible and this triggers the errors that you see.

The workaround is to source the modules init script again in your (job submission) script:
source /etc/profile.d/modules.sh
