} _canonical_paths_add_paths:6: no such builtin: stat

This must be happening because _canonical_paths_add_paths isn't actually
defined until _canonical_paths is executed, so the -U option to zcompile
doesn't have a chance to come into effect.

This is going to be a problem with any completion source file that has
multiple embedded function definitions.

It MIGHT help to both use "zcompile -a" and also change _canonical_paths
from using

    _canonical_paths_add_paths () {
      ...
    }

to using the load-once paradigm

    (( $+functions[__canonical_paths_add_paths] )) ||
    _canonical_paths_add_paths () {
      ...
    }

but I'm not confident of that.
