[Nano-devel] patch for multibuffer/view segfault

From: David Lawrence Ramsey
Subject: [Nano-devel] patch for multibuffer/view segfault
Date: Fri, 31 Jan 2003 10:34:35 -0800 (PST)

This patch fixes a potential segfault that occurs when using
multibuffer mode and view mode together, which used to be described on
DB's nano patches page.  To reproduce:

1. Open a file in multibuffer and view mode on the command line. [nano
-F -v file1.txt]
2. Read in a second file. [^R, file2.txt]
3. Close the second file. [^X]
4. Segfault.

It was, unfortunately, due to the last tweak I did to add_open_file()
(the "minor logic error" listed in the Changelog entry).  The code
didn't do exactly what the comment described, so I changed the code to
match it; it turns out that I should have changed the comment instead to
match the original code (which this patch does; I hope that doesn't
fall under cosmetic changes).
