Description
When building https://github.com/substrate-developer-hub/substrate-node-template , I've attempted to use the nightly version of Rust to speed up builds by using incremental compilation. Instead, I've encountered an ICE that suggested to create an issue.
Unfortunately, I was not able to minimize the error. I will try to minimize it, but the attempts to do so are hampered by extremely long build times. Which is why I would like to use incremental compilation in the first place.
Any directions on how to minimize the error are appreciated.
Code
These are the commands that can be used to reproduce the error:
# assuming debian/ubuntu, required dependencies
$ sudo apt install -y cmake pkg-config libssl-dev git build-essential clang libclang-dev curl
$ rustup target add wasm32-unknown-unknown --toolchain nightly
