The following macro generates a function fn f((_, _, …): (u8, u8, …)) {} with 4096 entries in the tuple.

macro_rules! long_tuple_arg {
    ([$($t:tt)*]#$($h:tt)*) => {
        long_tuple_arg!{[$($t)*$($t)*]$($h)*}
    };
    ([$([$t:tt $y:tt])*]) => {
        pub fn _f(($($t,)*): ($($y,)*)) {}
    }
}

It’s explicitly a stack overflow on stable 1.54 and AFAIK segfaults can happen on stack overflow in sound rust code, so maybe it isn’t some memory unsafety.

Digged a bit, this is indeed a stack overflow. Since rustc uses stacker, if we moved to a segemented stack instead of the native stack, std didn't know this is a stack overflow and so it appears as segfault instead.

The root cause is that compiler/rustc_mir_build/src/thir/pattern/usefulness.rs uses recursion.
