Hello Support Team and members, I have been debugging a crash for more than 2 months now and not able to find the cause or able to reproduce. data:text/text;charset=utf-8, # Cause: Crash due to signal: SIGSEGV(SEGV_MAPERR) at 0000000c # Reported at: 2021-07-23 04:22:58 UTC Thread 0 [Crashed]: 0 libobjc.A.dylib 0x1a8ccae2c AutoreleasePoolPage::AutoreleasePoolPage(AutoreleasePoolPage*) + 84 1 libobjc.A.dylib 0x1a8ccac2c AutoreleasePoolPage::autoreleaseFullPage(objc_object*, AutoreleasePoolPage*) + 59 2 libobjc.A.dylib 0x1a8ccaabc objc_object::rootAutorelease2() + 107 3 CoreAutoLayout 0x1a8f24e78 _engineVar_forVariable + 203 4 CoreAutoLayout 0x1a8f3813c -[NSISLinearExpression addVariable:coefficient:] + 59 5 UIKitCore 0x197f8c258 -[UIView(AdditionalLayoutSupport) nsli_lowerAttribute:intoExpression:withCoefficient:forConstraint:onBehalfOfLayoutGuide:] + 2999 6 UIKitCore 0x197f8b688 -[UIView(AdditionalLayoutSupport) nsli_lowerAttribute:intoExpression:withCoefficient:forConstraint:] + 307 7 CoreAutoLayout 0x1a8f42928 -[NSLayoutConstraint _lowerIntoExpression:reportingConstantIsRounded:] + 75 8 CoreAutoLayout 0x1a8f3ec90 -[NSLayoutConstraint _tryToChangeContainerGeometryWithUndoHandler:] + 171 9 CoreAutoLayout 0x1a8f3f4b0 -[NSLayoutConstraint _setSymbolicConstant:constant:symbolicConstantMultiplier:] + 403 10 CoreAutoLayout 0x1a8f3f8d0 -[NSLayoutConstraint setConstant:] + 91 11 UIKitCore 0x197f7e538 -[UIView(UIConstraintBasedLayout) _updateContentSizeConstraints] + 687 12 UIKitCore 0x197f87e94 -[UIView(AdditionalLayoutSupport) _updateSystemConstraints] + 123 13 UIKitCore 0x197f86c60 -[UIView(AdditionalLayoutSupport) _sendUpdateConstraintsIfNecessaryForSecondPass:] + 479 14 UIKitCore 0x197f87114 -[UIView(AdditionalLayoutSupport) _updateConstraintsIfNeededCollectingViews:forSecondPass:] + 943 15 UIKitCore 0x197f86ff4 -[UIView(AdditionalLayoutSupport) _updateConstraintsIfNeededCollectingViews:forSecondPass:] + 655 16 CoreAutoLayout 0x1a8f2a934 -[NSISEngine withBehaviors:performModifications:] + 79 17 UIKitCore 0x197f877cc _100-[UIView(AdditionalLayoutSupport) _updateConstraintsIfNeededWithViewForVariableChangeNotifications:]_block_invoke + 87 18 UIKitCore 0x197f861f0 -[UIView(AdditionalLayoutSupport) _withUnsatisfiableConstraintsLoggingSuspendedIfEngineDelegateExists:] + 119 19 UIKitCore 0x197f87418 -[UIView(AdditionalLayoutSupport) _updateConstraintsIfNeededWithViewForVariableChangeNotifications:] + 159 20 UIKitCore 0x197f883f0 -[UIView(AdditionalLayoutSupport) _updateConstraintsAtEngineLevelIfNeededWithViewForVariableChangeNotifications:] + 427 21 UIKitCore 0x198058524 -[UIView _updateConstraintsAsNecessaryAndApplyLayoutFromEngine] + 367 22 UIKitCore 0x19806b288 -[UIView(CALayerDelegate) layoutSublayersOfLayer:] + 2467 23 QuartzCore 0x19856eb2c -[CALayer layoutSublayers] + 287 24 QuartzCore 0x198574ff8 CA::Layer::layout_if_needed(CA::Transaction*) + 519 25 QuartzCore 0x198580314 CA::Layer::layout_and_display_if_needed(CA::Transaction*) + 139 26 QuartzCore 0x1984cc570 CA::Context::commit_transaction(CA::Transaction*, double, double*) + 415 27 QuartzCore 0x1984f66f8 CA::Transaction::commit() + 727 28 QuartzCore 0x1984f79a8 CA::Transaction::observer_callback(__CFRunLoopObserver*, unsigned long, void*) + 91 29 CoreFoundation 0x19527c86c _CFRUNLOOP_IS_CALLING_OUT_TO_AN_OBSERVER_CALLBACK_FUNCTION__ + 31 30 CoreFoundation 0x195276f40 _CFRunLoopDoObservers + 603 31 CoreFoundation 0x195277488 _CFRunLoopRun + 959 32 CoreFoundation 0x195276b90 CFRunLoopRunSpecific + 571 33 GraphicsServices 0x1ab599598 GSEventRunModal + 159 34 UIKitCore 0x197b60638 -[UIApplication _run] + 1051 35 UIKitCore 0x197b65bb8 UIApplicationMain + 163 36 Gojek 0x10228a840 main (VTGojekCreator.swift:52) 37 libdyld.dylib 0x194f55588 $start + 3 Thread 1: 0 libsystem_kernel.dylib 0x1c032a48c _workq_kernreturn + 8 1 libsystem_pthread.dylib 0x1db961874 $start_wqthread + 7 I added few logs in Crash reporting tools and looks like it is crashing while pushing the new controller but I can see looking at the logs that loadView of next view controller is not even getting called. I have had no luck reproducing it in local machine after thousand of tries across different simulator and devices. This crash is happening across the devices and iOS versions. Please help me out, I am feeling lost now.
