[Bug c++/33350] New: copy constructor error

[stevenyi at 163 dot com]

if the copy constructor is decrated with the key word explicit, the following
code won't compile,

struct T
{
explicit T() {}
explicit T(const T&) {}
};

void test(T const&)
{
}

int main(int argc, char *argv[])
{
test(T());
return 0;
}

(In reply to comment #1)
> Yes the copy constructor is going to be called implicately here.

the copy constructor is not actually called at runtime. and both intel compiler
and vc++ can compile this code.

I can not see any reason to call the copy constructor here. If you remove
keyword explicit so that let the code compile, you can find that the copy
constructor is not called at all.

This bug cause linux kernel unable to compile. So I think it must be fixed
before 4.3 is released
