Cargo not working in the last Nightly (64-pc-windows-gnu)

[leonardo-m]

Cargo shipped with yesterdays Nightly (it was rustc 1.30.0-nightly, 20dc0c507 2018-09-19, x86_64-pc-windows-gnu) was working fine. Today Cargo doesn't work to me. "Today" means rustc 1.30.0-nightly 3bc2ca7e4 2018-09-20.

...>cargo new foo1
error: Failed to create project `foo1` at `...\foo1`

Caused by:
  an unknown git error occurred

Beside giving that error it creates the foo1 directory with just a ".git" directory inside (that contains some files).

If I perform a "cargo build" inside a directory created by an older version of Cargo, it just crashes without error messages.

Thanks for the report! This should be fixed by alexcrichton/git2-rs@9c1604e and will be available once rust-lang/rust#54443 is merged and deployed!
