For the framebuffer UI issue mentioned in comment 7, it is now separately reported as bug #46949.

Current git version of Gnash is now playing and terminating properly with single-frame test SWF in oneshot mode. (Checked with GTK, Qt4, SDL, and Dump UI)

So, this bug could now be marked as fixed.

GTK GUI:

$ gtk-gnash -v --once singleframe.swf

Note: Gnash's framebuffer UI is not tested as there is an unrelated issue which caused it to leave the console screen unusable after it exited.

Fixed by patch #8858. I tested with gtk,qt4 and sdl guis.

After applied the first patch of patch #8858, you'd see that running
`gtk-gnash --once singleframe.swf` now terminates gracefully by itself:

See patch #8858, which also fix this issue.

With diagnostic patch from bug #27981 (`show-gtk-main-loop-level.patch`
file #36027), debug output shows that the freeze of this bug is also caused
by gtk-gnash trying to exit main GTK loop before `gtk_main()` was run;
the same root cause as bug #27981 minus window-related assertion warnings.

`gtk-gnash -vv --once singleframe.swf`:

Thus, when the real `gtk_main()` is run, nothing stops it.

See also bug #27981 (First-frame `fscommand("quit")` failure) which involves exiting on first frame in different way.

The previously-attached `singleframe.zip` mistakenly omitted binary SWF files,
sorry. SWF files are now included in the new `singleframe-swf.zip`.

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:

85 DEBUG: gnash::GtkAggGlue::GtkAggGlue() enter
85 DEBUG: gnash::GtkAggGlue::GtkAggGlue() returning
85 DEBUG: virtual bool gnash::GtkAggGlue::init(int, char***) enter

(gtk-gnash:20836): Gtk-CRITICAL **: IA__gtk_main_quit: assertion `main_loops != NULL' failed

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.
