Core dump in RawConnection drop

[Munksgaard]

Setup

Diesel needs to be able to connect to a database with a password. The error described below appears for me if the connection string is postgres://USER:PASSWORD@localhost/, but not if it is postgres://localhost/ or simpler forms thereof.

For my example, it was also necessary to add reqwest as a dependency: reqwest = "0.9.18"

Problem Description

Core dump when running program

What are you trying to accomplish?

I am running this program:

use diesel::pg::PgConnection;
use diesel::connection::Connection;

fn main() {
    let connection = PgConnection::establish("postgres://USER:PASSWORD@localhost/")
        .unwrap_or_else(|e| panic!("Error connecting to database, {:?}", e));

    let res = reqwest::get("https://example.com").unwrap();

    panic!("");
}

What is the expected output?

A normal panic

What is the actual output?

A normal seeming panic, followed by a core dump:

thread 'main' panicked at '', src/main.rs:10:5
