           Summary: Compiler crash on improper struct initialization
           Product: D
           Version: 2.030
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD

The following code fragment causes the compiler to crash with the following
useful information:

"dmd.exe has encountered a problem and needs to close.  We are sorry for the
inconvenience."

//--------------------
public S s = S();

public struct S {
    private int[] a = [ 0 ];
}
//--------------------

I realize the code is incorrect, but I expected an error message, not a
trainwreck.

Adding initializer information solves the problem:

//--------------------
public S s = S([0]); // compiles correctly

public struct S {
    private int[] a = [ 0 ];
}
//--------------------

Eliminating the forward reference solves the problem:

//--------------------
public struct S {
    private int[] a = [ 0 ];
}

public S s = S(); // compiles correctly
//--------------------

I think that removing the forward reference doesn't solve the problem.

If I add this line at the end:
void main() {}
The situation changes.

This was fixed in DMD 2.036.
