FIX: Error LNK2022: Metadata Operation Failed (8013118D) (324088)

The information in this article applies to:

Microsoft Visual C++ .NET (2002)

This article was previously published under Q324088

SYMPTOMS

When you declare anonymous structures globally and then compile the structures as managed code, you may receive the following (or similar) linker error messages:

error LNK2022: metadata operation failed (8013118D) : Inconsistent layout information in duplicated types ($ArrayType$0x1078d980): (0x02000002).
LINK : fatal error LNK1255: link failed because of metadata errors

CAUSE

This behavior occurs because the compiler generated incorrect metadata for these anonymous structures.

RESOLUTION

To resolve this problem, add unique identifiers when you use Managed Extensions for C++ so that you avoid using anonymous structures as global variables.

STATUS

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article. This bug was corrected in Microsoft Visual C++ .NET (2003).

MORE INFORMATION

The following code demonstrates the problem:

//c1.cpp
//Compiler option required: /clr
struct { int i; }a1[] = { {1}, {2}, {3}, {4} };
void FuncA(int i) { a1[i].i = i; }
//End of c1.cpp

//c2.cpp<BR/>
//Compiler option required: /clr
struct { int i,k; } a2[] = { {1,2}, {3,4}, {4,5}, {5,6} };
void FuncA(int);

void main() {
      FuncA(a2[1].k);
}
//End of c2.cpp
