println!(format!("")) causes infinite loop in compiler #12071

rcxdude · 2014-02-06T19:53:33Z

Attempting to compile:

fn main() {
    println!(format!("test"))
}

Causes rustc to go into an infinite loop printing out the same two lines:

testcase.rs:2:14: 2:20 error: macro undefined: 'format'
testcase.rs:2     println!(format!("test"))

The text was updated successfully, but these errors were encountered:

Closing as a dupe of #11692, but thanks for the report!
