Hi,

 I could reproduce the problem in #8522 and am using Emacs 24.3 with
 the patch in [*] (basically the same as one submitted in #8522) on
 FreeBSD.  It is working fine with no side effect.

 [*] http://svnweb.freebsd.org/ports/head/editors/emacs/files/patch-src_coding.c?view=markup&pathrev=281397
