bug#18161: 24.3.92; Crash in do_switch_frame

From: Mat Smiglarski
Subject: bug#18161: 24.3.92; Crash in do_switch_frame
Date: Fri, 01 Aug 2014 00:05:13 +0100
User-agent: Roundcube Webmail/1.0.1
Unfortunately I cannot invoke the crash from emacs -Q, so I have provided the following gdb output, which shows that there is a frame with no output_data, after calling `create-frame' with a nonsense `left' parameter. 

93 lines of a gdb session follows:

Emacs consistently crashes soon after startup when executing a
particular function
which happens to open a new frame.

Unfortunately I have not managed to reproduce this with emacs -Q. This
occurs on both trunk and the latest release candidate, but I don't
know if it is a regression.

Perhaps the backtrace has enough information, if not then let me know.

Regards,
Mat
