I’ve latest night build version of rustic:
libstd: rustc -v
rustc 0.10-pre-nightly (ff64381 2014-03-28 00:26:52 -0700)
host: x86_64-apple-darwin
Unfortunately, same error with `--cfg stage2`:
libstd: rustc --cfg stage2 lib.rs
num/int_macros.rs:231:1: 231:19 error: failed to find an implementation of
trait kinds::Copy for int
num/int_macros.rs:231 impl Int for $T {}
^~~~~~~~~~~~~~~~~~
num/int_macros.rs:14:1: 500:3 note: in expansion of int_module!
num/int.rs:27:33: 27:53 note: expansion site
Best regards,
Alexander
