The below ends with SEGV.
----------------------------
import std.stdio;

void logout( lazy const(char)[] msg ) { writeln( msg ); }
void main()
{
    string str = "hello world";
    logout( (){return str;}() );             // closure 1

    try throw new Exception( "exception!!" );
    catch( Exception e )
    {
        logout( e.toString );            // closure2 SEGV : e is null.
    }
}

----------------------------

Build : dmd 2.052 on Windows Vista WOW64.

Without `closure 1', the code executed successfully.
