Suspected infinite loop. No value used in loop test (c) is modified by test or loop body. Assignment of int to char: c = getchar() Test expression for if is assignment expression: c = 'x' Test expression for if not boolean, type char: c = 'x' Fall through case (no preceding br...

在以前版本的编译器中,此示例底部的静态断言可传递,因为 std::is_convertable<>::value 错误地设置为 true。 现在,std::is_convertable<>::value 正确设置为 false,使静态断言失败。 默认设置或已删除的日常复制和移动构造函数遵从访问说明符 对于默认设置或已删除的日常复制和移动构造函数的访问说明符,早期版本的...

The localeconv function declared in locale.h now works correctly when per-thread locale is enabled. In previous versions of the library, this function would return the lconv data for the global locale, not the thread's locale. If you use per-thread locales, you should check your use of loc...
