Subject: 24.0.50; Compilation mode broken, next-error not working

From: Jan Djärv <[email-masked]>

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the [email-masked] mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

(setq compilation-scroll-output t)
M-x compile (somewhere where you get warnings or errors).
M-x next-error
compilation-next-error-function: Wrong type argument: arrayp, nil

M-x compile
run-hooks: Wrong type argument: number-or-marker-p, nil

A second compile doesn't work until I kill the *compilation* buffer.
next-error never works.

Can the "compilation--flush-parse: 1 16056" messages be turned off?

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
     `bt full' and `xbacktrace'.
