bug in NSApplication

[Frederic De Jaeger]

Hi,

I often see gui apps crashing on quit.  So a decided to debug one to
see what's happened and I saw something that looks like a bug even if
it's not necessary the origin of all the crashs.

When I press 'Quit', it calls [NSApplication terminate] which destroy
the current application object.  But then, we are very deep in the
call stack :

#7  0x4044d0c2 in _i_NSObject__release (self=0x81a4a58, _cmd=0x402bcf30)
    at NSObject.m:1376

    sender=0x82f0168) at NSApplication.m:2311
#9  0x4044cde1 in _i_NSObject__performSelector_withObject_ (self=0x81a4a58,

    at NSApplication.m:1468

#13 0x4015df56 in _i_NSMenuView__mouseDown_ (self=0x82db158, _cmd=0x403032b0, 
    theEvent=0x8305d70) at NSMenuView.m:1116
#14 0x4021af4f in _i_NSWindow__sendEvent_ (self=0x82da428, _cmd=0x402bc7f0, 
    theEvent=0x8305d70) at NSWindow.m:2710
#15 0x400b3ed1 in _i_NSApplication__sendEvent_ (self=0x81a4a58, 
    _cmd=0x402bc520, theEvent=0x8305d70) at NSApplication.m:1383
#16 0x400b2239 in _i_NSApplication__run (self=0x81a4a58, _cmd=0x8071f00)
    at NSApplication.m:948

and as you can see, after the [NSApplication terminate] returns, we
are in frames that correspond to method call of objects which are all
dead...

maybe I do something wrong, should I RETAIN(NSApp) at the beginning of
my program and RELEASE(it) at the end?

Cordially,
