GCC converts reference to temporary when doing static_cast to void pointer reference

By -

GCC produces warning when compiling the following code:

void* const & cast(int* const &ptr)
{
    return static_cast<void* const &>(ptr);
}

The warning is "returning reference to temporary" (coliru).

Clang compiles the code without warnings (coliru).

Which compiler is right? And why is reference converted to temporary?

Also note that changing static_cast to reinterpret_cast fixes the warning (coliru).

Network Error and Timeout on Authorize.net JS

The problem arising now is that, going on the checkout page, I have the following console message: GET https://js.authorize.net/v3/AcceptUI.js net::ERR_NAME_NOT_RESOLVED Which is weird, cause I cannot ping the domain or anything, as my computer cannot resolve the domain. However, this issue is also reported by individual customers and it seems to be sporadically and not happening the entire time, cause i can see other orders going through. Does anyone know how such an error can be caused, or any ideas how it can be resolved? Thanks for your help EDIT: I just checked the A DNS record for js.authorize.net and am getting the following result only: js.authorize.net. 100 IN CNAME js.authorize.net.cdn.cloudflare.net.
