Panicking: Misaligned pointer dereference when sending client message

[cartoon-raccoon]

My program panics with a misaligned pointer dereference error when I try to send an event. I'm sending a ClientMessage event from the root window.

Attached is the rust backtrace of the panic, with irrelevant function calls removed: crashlog.txt

And this is the relevant code that's calling the function:

let event = x::ClientMessageEvent::new(
    // cast! is just calling <<type> as XidNew>::new(id)
    cast!(x::Window, window),
    cast!(x::Atom, data.type_),
    to_send // client message data
);

Ok(self.conn.check_request(self.conn.send_request_checked(
    &x::SendEvent{
        propagate: false,
        destination: x::SendEventDest::Window(cast!(x::Window, window)),
        event_mask: x::EventMask::NO_EVENT,
        event: &event,
    }
))?)

I am aware that cast! is calling unsafe code, but I'm fairly sure that all values that it's dealing with already exist on the server.

Have you tested with the main branch? This was very likely fixed by #229

[cartoon-raccoon]

I'm using v1.2.1 from Crates.io. I'll do some further testing with the latest commit on the main branch to see if it's fixed.

I was having a similar issue that was fixed by switching to the main branch.

Is there going to be a new release to make the fix available?

v1.2.2 is published
