vulkano: Bug after resizing window containing swap chain

I created a program using windows and the swapchain. The swapchain part is pretty similar to the triangle example. (I may upload it in git if you want to see. currently it’s just in pijul) The problem occurs after rendering, when calling this on some result: .then_signal_fence_and_flush().unwrap(); Then the window doesn’t update anymore, because it just stops there. When I wait some time, it generates an error message and a stack backtrace, I’ll include:

note: Run with `RUST_BACKTRACE=1` for a backtrace.

Ungültiger Maschinenbefehl (Speicherabzug geschrieben)

(The last line means something like “invalid machine command (core dumped)”)

I don’t think, this is a error, that should be able to occur without unsafe code, even if I did something wrong (what I don’t think, because except of using different shaders and doing additional things, it’s the same as the triangle example)
