Subject: 24.0.97; Crash with global-linum-mode and info
Date: Wed, 30 May 2012 15:35:35 +0200 (CEST)

[Message part 1 (text/plain, inline)]

Emacs will crash if global-linum-mode is enabled the first time I go to
the info directory. This can be reproduced every time using this sequence:

"C:\Program Files\GNU Emacs 24\bin\runemacs.exe" -Q
M-x global-linum-mode
C-h i

It seems like the crash happens every time a new info buffer is created.
If I first do C-h i and the M-x global-linum-mode it doesn't crash at the
next C-h i. However, it will then crash when I try to go to any info node.

I can't reproduce this on GNU Emacs 24.0.97.3 (x86_64-unknown-linux-gnu,
GTK+ Version 3.2.0).  Maybe a Windows-specific problem; could you
provide a backtrace?

Reproducible on Windows (24.0.97 and trunk).

I can reproduce it, and I'm working on a fix.

I think I fixed it, please test (revision 108024 on the emacs-24
branch).
