That explicit type conversion (i.e. cast) is equivalent to
reinterpret_cast<int>("") and the standard says reinterpret_cast can be used to
convert a pointer to an integer type large enough to hold it. The code is
invalid and should be rejected by any 64-bit C++ compiler, just as (short)""
should be by 32-bit compilers.
