总结 编译器警告 "error: this statement may fall through [-werror=implicit-fallthrough=]" 提醒开发者注意 switch 语句中可能存在的逻辑错误,即意外的 fall through。你可以通过显式地注释表明 fall through 是有意的,或者修改代码逻辑来避免不必要的 fall through,从而解决这个警告。
gcc编译错误this statement may fall through GCC编译器会在switch语句中检查case后是否需要添加break语句,以确保代码的正确性。当没有在case中加入break语句时,会出现警告信息”this statement may fall through”。这是因为如果没有添加break语句,程序会继续执行下一个case的代码,可能导致意想不到的结果。 解决这个问...
This warning notifies the programmer about the fall through. This warning option can be controlled with the GCC compiler switch -Wimplicit-fallthrough. It is not enabled by default and is not enabled by -Wall, but it is enabled by -Wextra. Warnings become errors if the -Werror switch is ...

When building the 2.2.2 version with GCC 8.3.0, it throws an error as seen in the screenshot below. The only non-patch solution for this was to add
