在 Rust 中使用 CryptUnprotectData 解密数据会导致STATUS_HEAP_CORRUPTION错误

问：

我正在开发一个函数，该函数接收并使用 .下面是有问题的函数：Rust&[u8]CryptUnprotectDataWinAPI

fn decrypt(data: &[u8]) -> Result<Vec<u8>, String> {}

我已经成功实现了这个功能，它成功地使用 .DPAPI

但是，我在尝试释放传递给 的缓冲区时遇到了一个问题。我收到以下错误：CryptUnprotectData

error: process didn't exit successfully: `target\debug\main.exe` (exit code: 0xc0000374, STATUS_HEAP_CORRUPTION)

下面是该函数的代码：

use winapi::{
    um::{
        winbase,
        dpapi,
        wincrypt
    },
    shared::minwindef
};

fn decrypt(keydpapi: &[u8]) -> Result<Vec<u8>, String> {
    // https://learn.microsoft.com/en-us/windows/win32/api/dpapi/nf-dpapi-cryptunprotectdata
    // https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-localfree
    // https://docs.rs/winapi/latest/winapi/um/dpapi/index.html
    // https://docs.rs/winapi/latest/winapi/um/winbase/fn.LocalFree.html

    let mut data_in = wincrypt::DATA_BLOB {
        cbData: keydpapi.len() as minwindef::DWORD,
        pbData: keydpapi.as_ptr() as *mut minwindef::BYTE,
    };
    let mut data_out = wincrypt::DATA_BLOB {
        cbData: 0,
        pbData: ptr::null_mut()
    };
    let result = unsafe {
        dpapi::CryptUnprotectData(
            &mut data_in,
            ptr::null_mut(),
            ptr::null_mut(),
            ptr::null_mut(),
            ptr::null_mut(),
            0,
            &mut data_out
        )
    };
    if result == 0 {
        return Err("CryptUnprotectData failed".to_string())
    };
    if data_out.pbData.is_null() {
        return Err("CryptUnprotectData returned a null pointer".to_string());
    }
    
    let decrypted_data = unsafe {
        Vec::from_raw_parts(data_out.pbData, data_out.cbData as usize, data_out.cbData as usize)
    };
    unsafe {
        winbase::LocalFree(data_out.pbData as minwindef::HLOCAL); // error occured here
    };
    Ok(decrypted_data)
}

我将不胜感激任何见解或解决方案来解决此错误。STATUS_HEAP_CORRUPTION
