           Summary: Compiler crashes when type is passed to writefln()
           Product: D
           Version: 2.023
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: ice-on-invalid-code
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: snake.scaly gmail.com


To reproduce, compile this:

import std.stdio;
struct Foo {}
void main()
{
    writefln(Foo);
}

The DMD crashes with access violation (read address 0x00000000)

Works for me, Windows DMD 1.042 and DMD2.027.
DMD2.027 doesn't refer to the source file which contained the error, but I
think that's normal behaviour and a quite different Phobos issue (Phobos
doesn't accept structs without toString().
