           Summary: Segfault using C-style struct initializer with too few
                    arguments
           Product: D
           Version: 2.027
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: accepts-invalid, ice-on-invalid-code
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: clugdbug yahoo.com.au


The bug is that it doesn't check that the number of members in the initializer
is correct. It's silently accepted as long as you don't access an uninitialised
member; if you do, the compiler segfaults.

----
struct Test{
 int foo;
}

enum Test test = {};
enum q = test.foo;

Fixed in DMD2.030, NOT FIXED in DMD1.045.

struct Test{
 int foo;
}

const Test test = {};
const q = test.foo;

Re-opened because DMD 1.045 segfaults.

Seems like this was just missed in copying from D2 to D1.
Segfaulting in StructLiteralExp::getFieldIndex() in expression.c.

PATCH: 
Just copy int StructLiteralExp::getFieldIndex(Type *type, unsigned offset)
(line 3197) from D2 to D1. (Needs if(elements->dim){ ... } around the for
loop).
