Any update on this? repros also on cargo 1.32.0-nightly (5e85ba14a 2018-12-02)

[gbip]

I think that it was solved by #7 😄

[cbeck88]

thanks :)

Does this actually fix the issue? I'm still seeing the error when I depend directly on this repository:

serde-json-core = { git = "https://github.com/japaric/serde-json-core" }

[Lawliet-Chan]

Does this actually fix the issue?
I meet the same error. My cargo.toml is
[dependencies] serde-json-core = "0.0.1"

And my rust version is
rustc 1.38.0-nightly (69656fa4c 2019-07-13)
rustup 1.19.0 (2af131cf9 2019-09-08)

@japaric: maybe this should be reopened.
