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.

The "x86_64" platform means the executable is 64-bit. Only Linux has 64-bit output.

BTW, reproducible on Mac OS X also.

Heh, on git HEAD (b9b5c063d7f44b879d6fde74f400ff094ba85707), this code causes
an ICE:

dmd: struct.c:251: static void AggregateDeclaration::alignmember(structalign_t,
unsigned int, unsigned int*): Assertion `alignment > 0 && !(alignment &
(alignment - 1))' failed.
Aborted

P.S. This is on Linux 64-bit.
