23.0.60; M-x compile gives args out of range 0, 0

["Jan Djärv" <jan.h.d@swipnet.se>]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

When doing M-x compile I get:
font-lock-extend-region-multiline: Args out of range: 0, 0

It seems to be random, sometimes I can compile in other directories, sometimes
not.  But args out of range comes about 3 times out of 4.  It seems to always
come in the emacs/src directory.

Debug-on-error t gives:

Debugger entered--Lisp error: (args-out-of-range 0 0)
   get-text-property(0 font-lock-multiline)
   font-lock-extend-region-multiline()
