           Summary: API returning immutable string on stack?
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: critical
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: turkeyman gmail.com



This code:
  string hash = std.digest.digest.toHexString(std.digest.sha.sha1Of("text"));

Does it seem reasonable that users should expect that 'hash' is on the stack?
As the program continues, 'hash' starts changing randomly.
hash.idup, it persists as expected.

A compilable test case that shows the problem would be helpful.

string func()
{
  string hash = std.digest.digest.toHexString(std.digest.sha.sha1Of("text"));
  return hash;
}

void main()
{
  string s = func();
  std.stdio.writeln("hello world"); // call a funtion
  std.stdio.writeln(s); // s is rubbish
}
