bash 4.2.25 (Ubuntu LTS 12.04) you can work around your issue with :

hi,

right!
as I had to deal with variables expanding to things like '\x3C', '%s' 
didn't work.

I tried '%b', and now I can see empty values.

thank you.

Thanks for the report.  A line got dropped from a merge back during
development.  I've attached a patch that fixes this and one other problem
with -R.

Thank you very much.

This is tremendous!

Do you mind explaining a little bit «the way Bash parses array subscripts» ?
