The spec talks about
"argptr, which is a void* pointer to the first of the variadic arguments. To
access the arguments, _argptr must be cast to a pointer to the expected
argument type: " ...

Although this was correct for 32 bits, it is now complete nonsense -- it
produces garbage on 64 bits. And it compiles silently.

I think this is the most severe spec bug ever.

And also the second example in the spec (involving core.vararg) doesn't
compile, because it refers to a non-existent print() function:

_arguments[i].print();
