Good to know. Duplicate radar filed, rdar://problem/21145343. We saw the same issue starting with 10.10.3 and continuing through current 10.10.4 builds. Write up a radar and reference radar://problem/20368338 as a duplicate instance. -- Gary L. Wade (Sent from my iPhone) http://www.garywade.com/

Document-based app, Deployment Target and SDK both 10.8. Built using Xcode 5.1.1 (5B1008) on Yosemite 10.10.3; running on the same system. Here’s what I do: 1. Run my app. 2. Open an existing document from disk. 3. Click on the document name in the window’s titlebar to open the Document name/tag/location popover. 4. Wait a second or two. 5. Click elsewhere in my document window to close the popover. 6. Crash. Sometimes the crash happens immediately after the popover disappears; other times it happens 1-3 seconds later. It doesn’t happen every time, but always within two to three repetitions of steps 3–5. Here’s the stack trace when it crashes: frame #0: 0x00007fff84a13d20 CoreFoundation`___forwarding___ + 768 frame #1: 0x00007fff84a13998 CoreFoundation`__forwarding_prep_0___ + 120 frame #2: 0x00007fff92603547 ViewBridge`-[NSRemoteViewBase endAllModalSessions:] + 177 frame #3: 0x00007fff925fbe74 ViewBridge`-[NSRemoteViewBase viewWillMoveToWindow:] + 367 frame #4: 0x00007fff864b90de AppKit`-[NSView _setWindow:] + 257 frame #5: 0x00007fff849ea705 CoreFoundation`__53-[__NSArrayM enumerateObjectsWithOptions:usingBlock:]_block_invoke + 133 frame #6: 0x00007fff849e9e09 CoreFoundation`-[__NSArrayM enumerateObjectsWithOptions:usingBlock:] + 313 frame #7: 0x00007fff86c3d474 AppKit`__21-[NSView _setWindow:]_block_invoke735 + 169 frame #8: 0x00007fff864b9c54 AppKit`-[NSView _setWindow:] + 3191 frame #9: 0x00007fff864c73d7 AppKit`-[NSVisualEffectView _setWindow:] + 214 frame #10: 0x00007fff86722747 AppKit`-[NSPopoverFrame _setWindow:] + 111 frame #11: 0x00007fff8670961f AppKit`-[NSWindow dealloc] + 1201 frame #12: 0x00007fff8679c9f5 AppKit`-[_NSPopoverWindow dealloc] + 74 frame #13: 0x00007fff864b68cc AppKit`-[NSWindow release] + 193 frame #14: 0x00007fff8497fdb0 CoreFoundation`CFRelease + 304 frame #15: 0x00007fff849a0bbd CoreFoundation`-[__NSArrayI dealloc] + 125 frame #16: 0x00007fff9211d89c libobjc.A.dylib`objc_object::sidetable_release(bool) + 236 frame #17: 0x00007fff92103e8f libobjc.A.dylib`(anonymous namespace)::AutoreleasePoolPage::pop(void*) + 575 frame #18: 0x00007fff849a16f2 CoreFoundation`_CFAutoreleasePoolPop + 50 frame #19: 0x00007fff8c1c1762 Foundation`-[NSAutoreleasePool drain] + 153 frame #20: 0x00007fff8650ccc1 AppKit`-[NSApplication run] + 800 frame #21: 0x00007fff86489354 AppKit`NSApplicationMain + 1832 After enabling Zombie Objects, I get the following in the console: 2015-05-28 14:19:58.291 MyApp[23684:2561441] *** -[NSDocumentTitlebarPopoverViewController isKindOfClass:]: message sent to deallocated instance 0x600000146f60 Google is no help, although it did uncover the following tweet from just a few days ago: https://twitter.com/tonyarnold/status/603424801152086017. Anybody run across this before, or have any thoughts on what the problem could be and/or how to debug? Thanks!
