我面临一个奇怪的问题，并且已经在此上花费了很多时间。
设备上的我的应用程序(特别是发行版)发生崩溃。

我了解存在一些与字节对齐有关的问题。但是对我需要做什么一无所知。
崩溃位置代码段是对的有效值函数调用:
static LtsEventStatus isBeaconInsideZoneAndDwellTime( const LtsBeaconProximityEvent* eventData,
const LtsBeaconProximity reportData, tSIRF_UINT8 isReverse, tSIRF_BOOL* found, tSIRF_UINT8 index)
任何帮助，将不胜感激。
谢谢

问题是根本没有打印日志“BeaconFence 42”。调用isBeaconInsideZoneAndDwellTime时，代码崩溃。在控制台日志中，我们得到sigbus 10
最佳答案
EXC_ARM_DA_ALIGN将指示您的代码正在尝试使用isbeaconInsideZoneAndDwellTime内部未正确对齐的变量。
从您对按值传递而不是地址传递的评论来看，这意味着isBeaconInsideZoneAndDwellTime内部的代码对LtsBeaconProximity结构的布局与调用它的代码具有不同的看法。当按值传递字节时，将复制它们，因此isBeaconInsideZoneAndDwellTime内部的代码正在处理其LtsBeaconProximity结构布局的版本。假设存在对齐问题，在这种情况下，您会在结构中看到错误的值，而不是SIGBUS。但是，如果错误值设为0或在未使用的区域中，您可能会摆脱它。通过地址传递时，isBeaconInsideZoneAndDwellTime内部的代码基于对LtsbeaconProximity结构布局的理解而使用偏移量和类型，但对理解该结构的调用代码使用偏移量。此处使用变量会触发对齐问题，因为两者必须不匹配。
我将在调用代码中添加一些调试信息，以打印出结构内容相对于起始地址和大小的偏移量。然后将相同的代码粘贴到isBeaconInsideZoneAndDwellTime中。如果代码未对齐，则会看到不同的偏移量。
一个简单的起点是在函数的内部和外部打印出sizeof(LtsbeaconProximity)。如果不同，则您知道它是一个问题。
如果您可以向我们展示LtsbeaconProximity的结构，那对我们有帮助。
