App crash on macOs with skia renderer

[windoze]

OS: macOs Sonoma 14.6.1 Machine: Mac Studio M1 Ultra

Reproduce steps:

1. Create an simple project with cargo generate --git https://github.com/slint-ui/slint-rust-template --name test-prj.
2. Change slint features in Cargo.toml to slint = { version = "1.7.2", default-features = false, features = ["std", "backend-winit", "renderer-skia", "compat-1-2"] }
3. Run app with cargo run or cargo run --release.

The app crash with no error message, only output:

    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.18s
     Running `target/debug/slint-rust-template`
zsh: segmentation fault  cargo run

I haven't digged into the issue, not sure if it's because Slint or Skia.

Could you try running lldb target/debug/slint-rust-template, then type r at the prompt, hit enter, and then paste the output you get there?

Sure.

Seems like null pointer was used at somewhere.

Thanks. Could you run bt on the same prompt after it crashed?

[windoze]

It shows basically nothing.

(lldb) bt
