I actually have this version :

> rustc 0.12.0-pre-nightly (25741603f 2014-08-03 23:46:10 +0000)

I actually don't really where the error comes from. It's in this repository : https://github.com/GuillaumeGomez/HTTP-Sender

I think it is in the http_sender.rs file in the function read_from_chunk. I added a fail! call at the line 40. It now gives this :

if self.data.len() > 1 && self.data[0] == 0u8 && self.data[1] == 0u8 {
    return Ok((0, self.data.len() - 1));
}
fail!("in !");
while pos < self.data.len() {

If you have anymore question, please ask. Good luck.

Nothing new on it ?

Do you happen to know if this still reproduces?

[GuillaumeGomez]

I just tried it again and the bug seems to be fixed. I close this issue then.

Thanks for checking!
