cargo insta test crash

[samueltardieu]

What happened?

After I put a insta::assert_snapshot!() in a function called by several tests, I got the expected

thread 'main' panicked at 'assertion failed: self.inline_snapshots.last().map_or(true, |x| x.end.0 <= line)', /home/sam/.cargo/registry/src/github.com-1ecc6299db9ec823/cargo-insta-1.26.0/src/inline.rs:60:17

introduced after #307.

However, after removing the insta::assert_snapshot!() from there, using cargo insta test still crashes:

$ RUST_BACKTRACE=1 cargo insta test --release

Reproduction steps

1. Put a insta::snapshot!() in a loop or a shared function.
2. Run cargo insta test and get an assertion error.
3. Remove the problematic insta::snapshot!().
4. Run cargo insta test and get another assertion error. At this stage you cannot use cargo insta anymore (unless you remove the pending snap file by hand)

Insta Version

1.26.0

rustc Version

rustc 1.69.0-nightly (e972bc808 2023-01-29)

What did you expect?

cargo insta test should work again when the problematic insta::assert_snapshot!() is removed from source.
