Well, you're not passing them in the normal way.  Try actually exporting
it from one bash instance to another, instead of setting the environment
variable contents by hand.

CentOS might have applied one of the experimental fixes that changes
*how* bash exports functions through the environment.  In which case,
this syntax would no longer be correct.
