Variadic parameters have been used on a non-C ABI function.
Erroneous code example:
```compile_fail,E0045
extern "Rust" {
fn foo(x: u8, ...); // error!
}
```
Rust only supports variadic parameters for interoperability with C code in its
FFI. As such, variadic parameters can only be used with functions which are
using the C ABI. To fix such code, put them in an extern "C" block:
```
extern "C" {
fn foo (x: u8, ...);
}
```
