Problem with update from 1.0.106 to 1.0.107 and higher

[hanusek]

Hello @dtolnay !
I have a problem updating the cxx library from 1.0.106 to 1.0.107. Problem with linking.

ARCH: arm

bindings.rs:

[...]
#[cxx::bridge]
mod ffi {
    #[derive(Debug)]
    struct Item 
    {
        pub key: String,
        pub value: String,
    }
    
    #[derive(Debug)]
    #[repr(i32)]
    /// Callback type
    pub enum CbType
    {
        UNREGISTERED,
        ERROR,
        BOOL,
        U8,
        U16,
        U32,
        U64,
        F32,
    }

    /// Generic Closure in C API
    pub struct CClosure
    {
        cb: *const c_char,
        cb_args: *mut c_char
    }

    #[derive(Debug)]
    /// CAN frame in C API
    pub struct CanFrame
    {
        id: u32,
        data: Vec<u8>
    }

    #[namespace = "rust_part"]
    extern "Rust" 
    {
        type Driver;

        unsafe fn create_driver(proto_spec: &CxxString) -> Result<Box<Driver>>;
        unsafe fn encode_cfg_frame(self: &mut Driver, frame_id: &CxxString, items: &CxxVector<Item>) -> CanFrame;

        fn encode(self: &mut Driver) -> Vec<CanFrame>;
        fn decode(self: &mut Driver, can_id: u32, data: &Vec<u8>);

        unsafe fn update_output_value(self: &mut Driver, var_index: &CxxString, slot_id: u8, state: bool) -> bool;

        fn valid_protocol(proto_spec: &CxxString) -> bool;
    }
}

Maybe there is a problem with https://docs.rs/cxx/latest/cxx/vector/trait.VectorElement.html ?
My element is:

 struct Item 
 {
    pub key: String,
    pub value: String,
}
