Minor: Compiler panic based on Cargo.toml "version" value #93779

Open rvthak opened 2 years ago

rvthak commented 2 years ago

Minimal reproduction

The bug appears while following this tutorial: https://docs.elrond.com/developers/tutorials/crowdfunding-p1/

  1. Install Elrond IDE extension on vscode (https://marketplace.visualstudio.com/items?itemName=Elrond.vscode-elrond-ide)

  2. On terminal: erdpy contract new crowdfunding --template adder code crowdfunding

  3. Open file Cargo.toml

  4. Set "version" to "0.0.1"

  5. Compile the code using erdpy contract build

  6. Compiler panics (It makes no sence)

  7. If you change "version" to something else (like 0.1.1) the problem self resolves.

  8. Setting the value back to "0.0.1" causes the compiler to panic again

Code

It doesn't seem to be affected at all by the rust code itself

``` Im a newbie to both rust and vscode and all the methods of setting RUST_BACKTRACE didn't seem to work for me. How do you properly set its value? ```

bjorn3 commented 2 years ago

This is probably related to incremental compilation. I think thid specific issue has already been fixed on nightly (and maybe beta) It is probably unrelated to version. I think it perturbed the input to rustc just enough to cause this issue.

I just hit an ICE that looks similar to the one reported here:

Removing the target folder and recompiling the entire project fixes the problem.

@msrd0 Did you force enable incremental compilation? As noted in https://blog.rust-lang.org/2022/02/24/Rust-1.59.0.html#incremental-compilation-off-by-default incremental compilation has been disabled in rustc 1.59 due to this kind of bugs. It should be fixed in rustc 1.60.

msrd0 commented 2 years ago

Yes, looks like I never removed the RUSTC_FORCE_INCREMENTAL variable from my bashrc since it was re-enabled by default after 1.52.1.

istankovic commented 1 year ago

@rvthak is this still relevant?
