`STATUS_ACCESS_VIOLATION` when cross-compiling for nightly-2024-02-19-aarch64-pc-windows-msvc when compiling `num-traits`

[chyyran]

Minimal reproducible example

fn main() {
    println!("Hello, world!");
}

[package]
name = "min-test"
version = "0.1.0"
edition = "2021"

[dependencies]
num-traits = "0.2.18"

cargo build --target aarch64-pc-windows-msvc

I expected to see this happen:
cargo builds the example

Instead, this happened:

PS F:\coding\min-test> cargo build --target aarch64-pc-windows-msvc

The last working compiler that I've tried was nightly-2024-01-15-aarch64-pc-windows-msvc. I haven't attempted to bisect since then so there could be some compilers working after 2024-01-15.

Reduced:

; RUN: llc -O0 < %s
target triple = "aarch64-pc-windows-msvc"

define float @test(float %x, i32 %n) {
  %res = call float @llvm.powi.f32.i32(float %x, i32 %n)
  ret float %res
}

declare float @llvm.powi.f32.i32(float, i32)

Does not reproduce on LLVM trunk.

Fixed by llvm/llvm-project@47c65cf and already backported upstream.
