If the FILE argument in `compilation-error-regexp-alist-alist`
is a function that returns nil on a matched line, then
`compilation-error-properties` throws an error when trying to
do a `string-match` against FILE and elements in
`compilation-transform-file-match-alist`.

It seems like there should be a check that the FILE is in fact
non-nil.

Quick recipe that should reproduce the error:

    (require 'compile)

    ;; function that is supposed to find appropriate file name
    (defun my-determine-file-name ())

    (define-compilation-mode my-mode "MM"
      (setq-local compilation-error-regexp-alist '(my-err))
      (setq-local compilation-error-regexp-alist-alist
                  '((my-err "\\([0-9]+\\):\\([0-9]+\\)"
                            my-determine-file-name 1 2))))

    (compilation-start "echo -e 1:2\n3:4" 'my-mode)
