 It is GC-related, the problem disappears with GC_DONT_GC flag set

 If I were to guess now it's about wrong gc_descr, something around
 object.c:493.

+A nicer testcase:
+
+struct Cont<T> {
+  public T f;
+}
+
+class C2 {
+  public Cont<string> c;
+
+  public C2 (int n) {
+    c.f = n.ToString () + "foo";
+  }
+}
+
+class M {
+  public static void Main ()
+  {
+    int n = 5;
+    C2[] ar = new C2[n];
+        for (int i = 0; i < n; ++i) {
+          ar [i] = new C2(i);
+      System.GC.Collect ();
+    }
+        for (int i = 0; i < n; ++i)
+          System.Console.WriteLine (ar[i].c.f);
+  }
+}
