    <p>I'm currently testing a new version of an app of mine on OSX 10.5 An user reported some weird crashes during use of the application, sadly not reproducible by me. At first sight it seems to happen randomly, once he had the crash while opening an NSOpenPanel and once during focusing an NSTextField and once during NSView switch in a parent view.</p> <p>If you have any idea which area I should look at it would be greatly appreciated! I'm completely lost here.</p> <p>App is compiled in XCode 3.2.1 with SDK 10.5 and targetted at 10.5</p> <p>Please note the issue isn't visible for hundreds of customers but for at least one it is. It's not in [openNZBFileButtonClick] only, the stacktraces seem to appear randomly even when clicking in an NSTextField once.</p> <p>He send me these crashes:</p> <p><strong>Crash 1</strong></p> <pre><code> Process: NZBVortex [43622] Path: /Users/cero/Downloads/NZBVortex.app/Contents/MacOS/NZBVortex Identifier: com.NZBVortex.NZBVortex Version: 0.5.5 (0.5.5) Code Type: X86-64 (Native) Parent Process: launchd [97] Interval Since Last Report: 1951 sec Crashes Since Last Report: 1 Per-App Interval Since Last Report: 1858 sec Per-App Crashes Since Last Report: 1 Date/Time: 2010-03-23 23:43:49.671 +0100 OS Version: Mac OS X 10.5.8 (9L31a) Report Version: 6 Anonymous UUID: 98AB0386-590B-4E0D-B7AC-3F7AA4E7238E Exception Type: EXC_BAD_INSTRUCTION (SIGILL) Exception Codes: 0x0000000000000001, 0x0000000000000000 Crashed Thread: 0 Application Specific Information: objc[43622]: alt handlers in objc runtime are buggy! - Hide quoted text - Thread 0 Crashed: 0 libobjc.A.dylib 0x00007fff82baef6e _objc_fatal + 238 1 libobjc.A.dylib 0x00007fff82bb2ea4 objc_addExceptionHandler + 302 2 com.apple.CoreFoundation 0x00007fff842b1090 _CFDoExceptionOperation + 528 3 com.apple.AppKit 0x00007fff81f75e26 _NSAppKitLock + 81 4 com.apple.AppKit 0x00007fff81f80f8f -[NSView nextKeyView] + 56 5 com.apple.AppKit 0x00007fff81f81018 -[NSView _primitiveSetNextKeyView:] + 72 6 com.apple.AppKit 0x00007fff820732b1 -[NSView _recursiveSetDefaultKeyViewLoop] + 242 7 com.apple.AppKit 0x00007fff82073300 -[NSView _recursiveSetDefaultKeyViewLoop] + 321 8 com.apple.AppKit 0x00007fff82073300 -[NSView _recursiveSetDefaultKeyViewLoop] + 321 9 com.apple.AppKit 0x00007fff82073300 -[NSView _recursiveSetDefaultKeyViewLoop] + 321 10 com.apple.AppKit 0x00007fff82073300 -[NSView _recursiveSetDefaultKeyViewLoop] + 321 11 com.apple.AppKit 0x00007fff82072fc3 -[NSView _setDefaultKeyViewLoop] + 279 12 com.apple.AppKit 0x00007fff82072e70 -[NSWindow recalculateKeyViewLoop] + 36 13 com.apple.AppKit 0x00007fff821dd149 -[NSSavePanel(NSSavePanelRuntime) _loadPreviousModeAndLayout] + 39 14 com.apple.AppKit 0x00007fff821dcf9e -[NSSavePanel(NSSavePanelRuntime) runModalForDirectory:file:types:] + 71 15 com.NZBVortex.NZBVortex 0x000000010000b7ee -[MainWindowViewController openNZBFileButtonClick:] + 62 16 com.apple.AppKit 0x00007fff821c96bf -[NSToolbarButton sendAction:to:] + 77 17 com.apple.AppKit 0x00007fff821c8bb7 -[NSToolbarItemViewer mouseDown:] + 5362 18 com.apple.AppKit 0x00007fff82082783 -[NSWindow sendEvent:] + 5068 19 com.apple.AppKit 0x00007fff8204fd46 -[NSApplication sendEvent:] + 5089 20 com.apple.AppKit 0x00007fff81faa562 -[NSApplication run] + 497 21 com.apple.AppKit 0x00007fff81f772f0 NSApplicationMain + 373 22 com.NZBVortex.NZBVortex 0x0000000100012a69 main + 9 23 com.NZBVortex.NZBVortex 0x0000000100001a84 start + 52 </code></pre> <p><strong>Crash 2</strong></p> <pre><code>Process: NZBVortex [43600] Path: /Users/cero/Downloads/NZBVortex.app/Contents/MacOS/NZBVortex Identifier: com.NZBVortex.NZBVortex Version: 0.5.5 (0.5.5) Code Type: X86-64 (Native) Parent Process: launchd [97] Interval Since Last Report: 727 sec Crashes Since Last Report: 1 Per-App Interval Since Last Report: 616 sec Per-App Crashes Since Last Report: 1 Date/Time: 2010-03-23 23:11:20.000 +0100 OS Version: Mac OS X 10.5.8 (9L31a) Report Version: 6 Anonymous UUID: 98AB0386-590B-4E0D-B7AC-3F7AA4E7238E Exception Type: EXC_BAD_INSTRUCTION (SIGILL) Exception Codes: 0x0000000000000001, 0x0000000000000000 Crashed Thread: 0 Application Specific Information: objc[43600]: alt handlers in objc runtime are buggy!

    2. COI'd check if it might be a 64-bit Leopard issue: If your user can reproduce it consistently, try getting them to run it in 32-bit mode instead (Get Info on the app, check "Open in 32 bit Mode"); also, make sure it's running in 64-bit mode on your own machine when you're trying to reproduce it.

    3. COQuote from site: "That's an error check inside the Objective-C runtime. Something has gone wrong inside the exception handling machinery, and it killed your process. You should file a bug report at http://bugreport.apple.com , and include a program that demonstrates this problem." Interesting,seems like I encounter something similar. I'll create a 32bit build for this user and ask him to try to reproduce.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
