linum + narrow = hang

linum + narrow = hang

Help!

I've been using emacs/Linux (usually RHEL) for many years and have always used c-x n n (narrow-to-region) and have used linum (global-linux-mode t in my init.el / custom-set-variables).   Lately, possibly since running on SUSE, emacs hangs if I try and narrow while linum is on.

It displays
Error in Post-command-hook (linum-update-current): (args-out-of-range 1 1)

The only way out seems to be kill -9 emacs-process.

Any ideas?  This is messing with my flow having to shut off linum.  Yes, I have the line number in the mode line but my compiler reports give errors with line numbers and it's much faster to see what's going on with linum.

Here's my config:
gnu emacs 24.5.1 x86_64-unknown-linux-gnu , GTK+ Version 2.18.9)
SUSE Linux Enterprise Desktop 11, Patchlevel 3

Thanks much,

 David

`M-x report-emacs-bug'.  Provide a step-by-step recipe to repro
the problem, starting with `emacs -Q'.

Thanks.  I ran with -Q and then manually loaded parts of my init.el.   It turned out to be in the custom-set-face section.  Specifically, the default font included setting a box around it:

:box (:line-width 1 :color "black")

I did this because I had put boxes around other font faces since I liked how it looked in various modes and I had to put the same size box around default face or text didn't line up anymore.   If I comment out that one line of my init.el, everything is fine.  So there's some odd interaction between linum and narrow if there's a box around default!

This is now fixed for the next release.  Thanks for a detailed report.
