I create a simple project to demonstrate C++ code crash symbolication.The C++ code is crash.cpp:#include "crash.h" #include int* newPtr() { return new int[1]; } void resetPtr(int** ptr) { *ptr = nullptr; } void usePtr(int* ptr) { int var = *ptr; var++; *ptr = var; } void testCrash() { int* ptr = newPtr(); usePtr(ptr); resetPtr(&ptr); usePtr(ptr); resetPtr(nullptr); usePtr(ptr); }The Objective-C code calling it is ViewController.mm:#import "ViewController.h" #import "crash.h" @interface ViewController () @end @implementation ViewController { int _val; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. // this could be symbolicated correctly //ViewController* vc = nil; //NSLog(@"%d", vc->_val); // this couldn't be symbolicated correctly testCrash(); NSLog(@"test"); } @end The line number above is the same as source code. It should crash at ViewController.mm:22 => crash.cpp:23 => crash.cpp:14, and that's exactly what I see in Xcode when I run the app in Xcode.But when I disconnect with Xcode, and launch the app from home screen, then get the crash log using Xcode menu Window - Devices and Simulators - View Device Logs, but the symbolicated crash is:Thread 0 name: Dispatch queue: com.apple.main-thread Thread 0 Crashed: 0 CrashExample 0x000000010493230c usePtr(int*) + 25356 (crash.cpp:13) 1 CrashExample 0x000000010493234c testCrash() + 25420 (crash.cpp:24) 2 CrashExample 0x0000000104932480 -[ViewController viewDidLoad] + 25728 (ViewController.mm:23) 3 UIKitCore 0x000000018ea0a36c -[UIViewController _sendViewDidLoadWithAppearanceProxyObjectTaggingEnabled] + 104All 3 frames are wrong!I'm using Xcode 11.4.1 (11E503a), macOS 10.15.4 (19E287), iPhone 11 iOS 13.4.1.Here is my test project: https://imgs.piasy.com/2020-05-16-CrashExample.zipPlease help me, thanks!
