           Summary: std.format.doFormat + struct without toString() == crash
           Product: D
           Version: 1.010
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: fvbommel@wxs.nl


When formatting a struct instance, std.format.doFormat doesn't check whether TypeInfo_Struct.xtoString is null before calling it. IMHO it should check for this and throw an exception if it's null.
