Hi Lauri,

This is fixed in the devel branch (bash v4.4). I can confirm the issue in v4.3:

This is not a bug. When you use shopt -s extglob, you change how bash parses
the input script. But it has some restrictions:
- You can't enable extglob and use extglob syntax in the same line
- You can't enable extglob in a function

There is no bug. Simply, your expectations on when the DEBUG trap runs are

I don't think so, unless Debian turned it on for me.
Can you test with:
bash --norc --noprofile -i
Note that without a\ a.odt there,
$ ls ~/a/aTAB[completes to a\ a.txt]
but
$ ls ~/a/a\ TAB

I was playing with the following scenario:
IFS set to backslash,
using read (with and without -r),
triggering field splitting by passing multiple names to read,
triggering field splitting by expanding an unquoted parameter.
And, I found the following results:
