我遇到了同样的问题。

似乎这是一个已知问题，与MinGW相关，并且已在JetBrains跟踪器中发生错误：

Seems like it is a known issue, related to MinGW and bugged in JetBrains tracker: https://youtrack.jetbrains.com/issue/CPP-2580#u=1443705085694

IDE只是一个问题/显然，如果在IDE外部运行，程序将正常运行。

It is just an issue with IDE / terminal obviously, program will run properly if run outside of the IDE.
