Minimal code (error is index out of bounds: the len is 61 but the index is 66):

#[plugin]
extern crate regex_macros;
extern crate regex;

static R : regex::Regex = regex!(r".+");

fn main() {
    println!("Hello, world!");
}

Cargo.toml:

[dependencies]
regex = "0.1.10"
regex_macros = "0.1.5"
log = "0.1.9"

[tamird]

Unable to repro:

#![feature(plugin)]
#![plugin(regex_macros)]

extern crate regex;

static R : regex::Regex = regex!(r".+");

fn main() {
    println!("Hello, world!");
}

Compiles now.

Seems like the ICE was somewhere in regex-macros, and is now either fixed or worked around. @steveklabnik maybe close this? Doesn't look actionable.
