@Laurențiu Nicola I still can't get the panic in my machine even I switch to nightly. I am using Windows, maybe it is the different ?
Possibly. I'm using a random nightly (
2020-12-09). Maybe there's been another proc macro ABI change? I seen to recall an issue about it.
Im using 2020-12-19 nightly, let me change to 2020-12-09 and test it again
No luck, I still cant reproduce that even in 2020-12-09 nightly :(
I finally can reproduce it when using wsl and nightly rustc ! I will take a look later.
Yeah, after tons of gdb debugging, the error is very simple actually. They changed the abi in https://github.com/rust-lang/rust/pull/75082. And the changed is also landed in stable 1.48, so I will make a PR for that.
