bindgen link wrong destructor in windows

Input C/C++ Header

class RustCThostFtdcMdSpi:CThostFtdcMdSpi
{
public:
	void *RustObject;
	RustCThostFtdcMdSpi(void *RustObject)
}
RustCThostFtdcMdSpi::RustCThostFtdcMdSpi(void *RustObject):RustObject(RustObject){}
RustCThostFtdcMdSpi::~RustCThostFtdcMdSpi(){}

but the right address is 'RustCThostFtdcMdSpi@@QEAA@XZ'

Bindgen Invocation

  let bindings = bindgen::Builder::default()
      .header("src/wrapper.hpp")
      .derive_debug(true)
      .derive_default(true)
      .generate()
      .expect("Unable to generate  bindings");

the bindgen function is

extern "C" {
    #[link_name = "\u{1}??_DRustCThostFtdcMdSpi@@QEAAXXZ"]
    pub fn RustCThostFtdcMdSpi_RustCThostFtdcMdSpi_destructor(this: *mut RustCThostFtdcMdSpi);
}

but the right link address is RustCThostFtdcMdSpi@@QEAA@XZ

I guess there is something wrong

Start with the C++ declaration in src/wrapper.hpp and the bindgen::Builder invocation shown in the issue. Inspect the generated extern block and compare the destructor's Windows link_name with the expected symbol address. Done means bindgen emits the correct destructor symbol for this input without breaking related C++ destructor bindings.
