An ICE shows up when compiling hello_world with parallel rustc.
When built with RUSTFLAGS="-Z threads=N", where N>1, triggers the ICE.

Code

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

Meta

What stands out on my machine may be that I am running:

Linux kubus 6.6.1-060601-generic #202311151749 SMP PREEMPT_DYNAMIC Thu Nov 16 03:15:36 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

And have in env

RUSTFLAGS=-Z threads=8
MALLOC_CONF=thp:always,metadata_thp:always

Since the backtrace mentions clone3, I tried MALLOC_CONF="" which resulted in the same ICE.
The backtrace also mentions rayon. I tried RUSTFLAGS=-Z threads=1, which results in a succesful build and suggests parallel rustc is related.

However, given how easy it is to provoke and considering I did not find other issue describes or resembling this ICE seems to indicate this may have sometihng todo with my setup.
