For following script:

With bash 4.1 it outputs hello but with 4.2 it outputs [hello . And bash 4.2
with compat41 on still outputs [hello . Bug? Or Bug fixed?

This is strange.  It echoes "hello" on Mac OS X, but "[hello" on
Red Hat.  I'll have to take a look at where the difference might be.

Just to rule out it being Linux specifc, I get the expected "hello" on Arch Linux.
