Public bug reported:

Steps to reproduce:

Type
find -exec<TAB>
where <TAB> is a literal Tab, results in the error
-bash: COMP_WORDS: bad array subscript
being printed (to stderr?)

Expected:

Probably no-op, since both -exec and -executable are valid flags.

Instead:

-bash: COMP_WORDS: bad array subscript
Is "auto-completed", except it's not. I'm guessing it's written to stderr.
