`completion-boundaries` should not need to perform a `dabbrev--search`.
Which version of Emacs is that?
It would be useful to figure out what is this
#<compiled 0x1f4100e4f6213ad7> function (presumably a completion-table)
and how it calls `complete-with-action` because normally it should call
it with an argument of the form `(boundaries . N)` which should cause
`complete-with-action` to return nil immediately.
