+I managed to make a smaller test case, still using mcs though.
+
+mono mcs Test1.cs Test2.cs
+

+You can download the source files from here:
+www.otee.dk/joe/reproduce_ppc_crash.zip
+
+or alternatively use the code inlined here:
+
+---Test1.cs
+using System.Collections;
+---
+
+---Test2.cs
+using System.Collections;
+
+class Mesh
+{
+	public int[] triangles;
+}
+
+public class MeshCombineUtility {
+	
+	public struct MeshInstance
+	{
+		int i;
+	}
+	
+	public static int Combine (MeshInstance[] combines)
+	{
+		int triangleCount = 0;
+	
+		int[] triangles = new int[triangleCount] ;
+	
+		Mesh mesh = new Mesh();
+		mesh.triangles = triangles;
+		
+		return triangles.Length;
+	}
+}
