Closed duelinmarkers closed 10 years ago

duelinmarkers commented 10 years ago

With these versions:

$ rustc -v
rustc 0.12.0-nightly (43fd61981 2014-09-22 23:50:30 +0000)
$ cargo version
cargo 0.0.1-pre-nightly (a54cb70 2014-09-23 01:34:57 +0000)

I get these errors:

Could not compile `persistent`.
