bug#19435: SIGSEGV in PSEUDOVECTOR_TYPEP when using find-file on a RTL f


From: Ivan Shmakov
Subject: bug#19435: SIGSEGV in PSEUDOVECTOR_TYPEP when using find-file on a RTL filename
Date: Wed, 24 Dec 2014 07:25:04 +0000
User-agent: Gnus/5.13 (Gnus v5.13) Emacs/24.3 (gnu/linux)

Package: emacs

        As of 36c43e95de5e (2014-12-18 16:44:11 +0000), Emacs segfaults
        when trying to use find-file on "\u062f\u0646\u06cc" (encoded as
        a ASCII-safe Emacs string literal here.)

        Strangely enough, $ emacs -Q handles that filename just fine.

        The backtrace is MIMEd.
