Details:

I have created a simple one-frame Flash 7 file using SWFmill, and run it
on Gnash using oneshot mode:

gtk-gnash -vv --once singleframe.swf


Gnash supposed to render this one-frame SWF and exit. Window was briefly
displayed and quickly vanished as expected, but instead of exiting
gracefully,
*Gnash froze*, and command-line interrupt (Ctrl+C or Ctrl+\) was needed to
exit.

Following is a console output:

Test SWF, source code, build script, Gnash log (verbosity 2) and GDB
backtrace
(collected from SIGQUIT core dump) are attached.

Note #1: `qt4-gnash`, and `dump-gnash` don't seem to be affected by this
issue.
Note #2: `gtk-gnash -vv --once` seems to work well with two-frame SWF.

Gnash: 0.8.11dev (git f0f66ce 23-Sep-2015)
System: Debian GNU/Linux 7.0 Wheezy i386
