os_malloc导致致命异常29(StoreProhibitedCause)怎么解决？

我正在尝试在 ESP8266 中使用 C++ 进行编译。经过大量搜索，我已经设法从 jcmvbkbc 安装了 xtensa c++ 编译器（当然是很棒的工作），其中包括：
所以，完成这些事情后，我可以毫无错误地编译我的 C++ 代码，但是，当我将它上传到我的 NodeMCU 时，它会抛出一个致命异常 29。经过一些代码更改和许多实验后，我发现
创建对象导致异常。为了获得更多信息，我使用了 Espressif Github 的 GDB Stub。然后，我尝试在 gdbstub_init() 之后创建一个对象，我使用 GDB 中的 step 函数检查了每一行代码，我得到了这个输出：

所以，似乎是 pvPortMalloc 导致了异常。
有任何想法吗？
