Test case for the layout issue.
I have a struct that contains four Mono.Simd.Vector4f fields. I'm using it as a
pointer into unmanaged code.
[StructLayout (LayoutKind.Sequential)]
struct Matrix {
public Vector4f col0, col1, col2, col3;
}
The problem is that on Mono, the address of the first field is not the same as
the address of the struct, despite using LayoutKind.Sequential. This means that
code that works on .NET does not work on Mono.
A test case is attached.
