iOS端sigsegv（segv_访问）上的小概率崩溃事件

我的问题是如何定位崩溃的特定函数指令，就像系统函数有崩溃的汇编指令堆栈一样；或者，为了分析可能的原因，我个人认为可能是*错误指针在另一个线程中被释放了，这就是野生指针问题，但是如何验证它呢

其中projectName表示项目名称，表示它是项目的内部功能，而不是系统功能

崩溃堆栈信息如下所示：

崩溃线程###0线程## 西格塞格夫 塞格沃·阿克尔

从堆栈上看，这似乎是启动时造成的崩溃

通过计算偏移量“*error=[NSError errorWithCode:-10 message:@”来指定崩溃线文件路径为空“]；”

    - (NSData *)dataForPath:(NSString *)filePath error:(NSError *__autoreleasing *)error {
            if (filePath == nil) {
                if (error) {
                    *error = [NSError errorWithCode:-10 message:@"文件路径为空"];
                }
                return nil;
            }
            ...
    }

    + (instancetype)errorWithCode:(NSInteger)code message:(NSString *)message {
        return [NSError errorWithDomain:NSLocalizedDescriptionKey code:code message:message];
    }
