          Issue ID: 16783
           Summary: std.net.curl application throws an exception
           Product: D
           Version: D2
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: phobos
          Assignee: nobody puremagic.com
          Reporter: farukerdemoncel gmail.com

I try to compile this program from std.net.curl

import std.net.curl, std.stdio;

void main()
{
    auto range1 = byLineAsync("www.google.com");
    auto range2 = byLineAsync("www.wikipedia.org");
    foreach (line; byLineAsync("dlang.org"))
        writeln(line);

    foreach (line; range1) writeln(line);
    foreach (line; range2) writeln(line);
}

I compile this program like this.

    $ dmd internet.d -ofinternet

or

    dmd -I/usr/include/dmd/phobos -L-l:libcurl.so.4.2.0 internet.d -ofinternet

The program compiles fine but it throws an exception.

Sometimes it prints the web page's html content as expected but again it throws
this exception.

Steps to Reproduce:
1) Run Ubuntu 12.04 from memory stick.
2) Fresh install dmd
