It's incorrect to call the function by its name in the interceptor, because that means WRAP(vname) on Linux and REAL(vname) on OSX.

Fix an ODR violation in the sanitizer runtimes.
...
A helper function is a C++ function, and so even though one of the two
definitions is weak, it still technically triggers the ODR. Perhaps
these two definitions are ODR equivalent, but I'm not even confident in
that.
Instead, just define the function once, declare it as weak, and use
a wrapper that is clearly file-local. This avoids two definitions. Also
make the function extern "C" so that we can't even mess up the type
signature somehow or otherwise fail to match up the weak declaration
here with the interceptor defined elsewhere.
