          Issue ID: 15809
           Summary: Putting std.stdio.File.ByLine ina class causes Invalid
                    memory operation upon exit
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: regression
          Priority: P1
         Component: phobos
          Assignee: nobody at puremagic.com
          Reporter: hsteoh at quickfur.ath.cx

Reduced code:
------
import std.stdio;
class Wrapper
{
    typeof(stdin.byLine()) src;
}
void main()
{
    auto x = new Wrapper();
    x.src = stdin.byLine(); 
}
------

Compiled with git HEAD, upon program exit, the following error is triggered:
------
core.exception.InvalidMemoryOperationError at src/core/exception.d(693): Invalid
memory operation
------

Commenting out the second line in main() makes the problem go away.

Works with older releases of dmd toolchain.
