          Issue ID: 16654
           Summary: hashOf returns different hashes for the same string
                    value
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: major
          Priority: P1
         Component: druntime
          Assignee: nobody puremagic.com
          Reporter: dev nomad.so

The following assert fails:

import std.stdio;
import std.conv;

void main(string[] args)
{
    auto x = 1;

    assert(hashOf(x.to!(string)) == hashOf(x.to!(string)));
}

This is because numeric values of the pointers to the strings are being
included in the hash calculation.
