c++ - FreeRTOS 仅在 Release 中崩溃

Question

我的代码仅在发布时崩溃:

int main() 
{
  MyStruct s;
  s.field = bla;

  xTaskCreate(TestTask, "TestTask", 2000, &s, 1, 0);

  // other tasks creation
  vTaskStartScheduler();
}


void TestTask(void *p) 
{
  // some delay
  MyStruct* s = (MyStruct*)p;
  another_func(s->field); // hard fault
}

我设法像这样修复它:

int main()
{
  MyStruct* s = new MyStruct();
  s->field = bla;
  xTaskCreate(TestTask, "TestTask", 2000, s, 1, 0);

  // other tasks creation
  vTaskStartScheduler();
}

我不明白为什么。我是否修复了它或解决了仍然存在的内存损坏问题？

谢谢。

我傻了，FreeRTOS的文档上写的: https://www.freertos.org/a00125.html

so it is not valid to pass the address of a stack variable.
