bug#18848: 24.4.51; Hang after toolbar use |

Emacs hangs reliably when I
Emacs -Q
double-click on a toolbar icon such as “Search”.
Inspecting this a little, I get this backtrace when I interrupt the process:

Setting a breakpoint on handle_async_input I see that this function doesn’t get
called (during the hang) unless I move the mouse over the mode line. The
keyDown: method in nsterm.m does get called and runs as expected.
During the non-hang (normal) condition, I can see that toolbarClicked: runs
twice and puts its events in the queue. I don’t know the Emacs-side event
handling well enough to inspect this further.
This is Emacs built with “-O0 -g” from git revision 46b813 [that’s for the
official git repository at this point], but users have reported similar
problems with Aquamacs based on 24.4.1. They do not mention double-clicks -
but they often use the toolbar. Double-clicks are just a very reliable way for
me to reproduce the problem.
If this is not reproducible, please let me know and I’ll help.
