我在RT-Thread Studio2.0下，创建了一个RT-Thread4.0.2版本的QEMU-VExpress-A9项目，当我使用C++的标准输出流cout出现异常情况,我之前在STM32407上是正常使用的，希望官方能够看到并解决。
异常报错情况：
```
E:\IDE\RT_Thread\QEMU-VEXPRESS-A9_Project>D:/ProgramData/RT-ThreadStudio/repo/Extract/Debugger_Support_Packages/RealThread/QEMU/4.2.0.4/qemu-system-arm.exe -M vexp
ress-a9 --kernel Debug/rtthread.bin -nographic -show-cursor
