           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).
