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)
