Unknown Compiler Error

[kyledj]

Receive a very cryptic compiler error with the following code

use core::option::Option;

enum Something {
    Value(~str),
    Other(int)
}

struct Record {
    num: int,                
    start: Option<RecordValue>
}

struct RecordValue {
    value: Something,
    next: Option<RecordValue>
}

fn main() {
}

The output:

rust: task 7f8fe2600fc0 ran out of stack
error: internal compiler error: unexpected failure
note: the compiler hit an unexpected failure path. this is a bug
note: try running with RUST_LOG=rustc=0,::rt::backtrace to get further details and report the results to github.com/mozilla/rust/issues
rust: task failed at 'explicit failure', /Users/kylejones/src/rust/rust/src/rustc/driver/rustc.rs:241

You need to change the type of the start and next fields to Option<@RecordValue>. The compiler should be giving you a nicer error message here, but there's already a bug open on it: #3779 .

Thanks for the report!
