Version: 117
Platform: Windows 11 (x64)

Using -O2 and higher on Windows produces UNREACHABLE executed at Precompute.cpp:838 error.
I've attached the binary that helps to reproduce the behavior.

stardew-valley-designer-app-web-wasm-js.wasm.zip

To reproduce the failure, take the binary and run the following command:

wasm-opt.exe --all-features -O2 .\stardew-valley-designer-app-web-wasm-js.wasm -o output.wasm 

To generate the binary by yourself:

1. Clone repo: https://github.com/AzimMuradov/stardew-valley-designer
2. Create local.properties file with the following content: kotlin.daemon.jvmargs=-Xmx2048m
3. Run ./gradlew.bat :app-web:compileProductionExecutableKotlinWasmJs
4. The binary is located in the following directory: app-web\build\compileSync\wasmJs\main\productionExecutable\kotlin
