Starting from `emacs -Q` with a NextStep build (well, Cocoa actually)
run M-x shell RET and every half second the following message is printed
to the console:

2012-08-21 12:26:07.872 Emacs[58915:3403] *** __NSAutoreleaseNoPool(): Object 0x1007c9200 of class NSEvent autoreleased with no pool in place - just leaking

Setting the environment variable NSAutoreleaseHaltOnNoPool=YES and
running under gdb I get the following backtrace:
