--- Comment #7 from Yu Xuanchi <yuxuanchiadm at 126 dot com> --- And there is another option. Because clang documentation say: "However, when an overloadable function occurs within an extern "C" linkage specification, it’s name will be mangled in the same way as it would in C." So should we think nested function as implicit extern "C" and mangled it in C way like "test.0000", "test.0001"?
