查找使用constexpr的代码行: 在C语言文件中找到所有使用constexpr的地方。例如: c constexpr int MAX_SIZE = 100; // 这行代码在C语言中会导致编译错误 替换constexpr为C语言中合法的关键字或移除它: 由于C语言不支持constexpr,我们需要移除它,或者使用C语言中的其他机制来实现相同的功能。如果conste

This appears to be only a problem with MSVC and Clang; currently small_string (and small_vector) do not explicitly initialize their std::array<> storage, which means the values (if POD) are un-initialized. This isn't allowed for a constexpr value. This could be fixed by doing the ...
