use_after_free issue with nightly about cargo-aoc HOT 6 CLOSED

@jfredett Looks like you are using edition 2018 with an older version of aoc-runner-derive.

This issue should be solve in 0.1.3.

from cargo-aoc.

That did it, I can confirm that the nightly-2018-11-30 works as expected as a workaround for this issue.

Thanks for reporting !

I have reproduce the issue on last nightly, I had a different message with a 2-3 day old one.

I'll check that :)

from cargo-aoc.

Ok, made some progress.

proc_macro is under refactor, see https://github.com/rust-lang/rust/tree/master/src/libproc_macro.

I'm not sure if it's a bug or an expected behavior (at least it should fail to compile aoc-runner-derive crate...), so I will open an issue, and recommend you to use an older nightly build.

I'm working my way through recent nightlies (I'm also seeing this problem on most recent nightly), but I'm getting a different issue.

≈≈≈ cargo build

error: aborting due to previous error

This happens on 2018-11-25 nightly, I'm still working my way through the others, but I'm wondering if my setup is just wrong?

here's my day1.rs from whence the above error comes:

pub type SignalChain = Vec<i64>;

#[aoc_generator(day1)]
pub fn input_generator(input: &str) -> SignalChain {
   // snip
}

#[aoc(day1, part1)]
pub fn solution(input: &str) -> i32 {
    // snip
}

I haven't really got to use the framework much (trying to work through the issues getting it to run), so it may just be that I'm doing something wrong/missing some use?

from cargo-aoc.

I just published aoc-runner-derive 0.1.4, which solves this problem !
