REPL always print the same result as [out0]

[cmal]

Hi, I installed papyrus using the follow command on Mac OS X, repl always print the same result as [out0].

$ cargo +stable install papyrus --no-default-features --features="format,runnable"

[lib] papyrus=> 2 + 2 papyrus [out0]: 4 [lib] papyrus=> "xxx" == "xxx" papyrus [out1]: 4 [lib] papyrus=> 1 == 3 papyrus [out2]: 4 [lib] papyrus=> 2 + 3 papyrus [out3]: 4

Hi @cmal, thanks for the bug report. I am unable to reproduce on Linux or Windows.

What version of Rust are you running?

Hello,

Can't speak for @cmal but I found the same problem. Same version of MacOS, initially using v1.43.1, now using 1.44.1 of Rust.

Whatever is displayed in the first return output is then always displayed for every consecutive test.

$ papyrus
[lib] papyrus=> 2 + 3
papyrus [out0]: 5
[lib] papyrus=> 2 + 2
papyrus [out1]: 5
[lib] papyrus=> 1 + 1
papyrus [out2]: 5
[lib] papyrus=>

Poking around I looked at the ~/.papyrus/src/lib.rs file and it's capturing output as:

#[no_mangle]
pub extern "C" fn _lib_intern_eval() -> kserd::Kserd<'static> {
let out0 = 2 + 3;
let out1 = 2 + 2;
let out2 = 1 + 1;
kserd::ToKserd::into_kserd(out2).unwrap().into_owned()
}

Met the same issue. I use MacOS.
