 I couldn't repro the problem, so I just disabled the GC_stackbottom
 setting code for now. Could you try this patch and see if it fixes the
 problem for you:

+I have applied the above patch - now mini.c 
+(appropriate fragment) looks like:
+
+if (getenv ("MONO_DEBUG") != NULL)
+		mini_parse_debug_options ();
+
+	/*
+	 * Handle the case when we are called from a thread different from
+the main thread,
+	 * confusing libgc.
+	 * FIXME: Move this to libgc where it belongs.
+	 *
+	 * we used to do this only when running on valgrind,
+	 * but it happens also in other setups.
+	 */
+#if defined(HAVE_BOEHM_GC)
+#if defined(HAVE_PTHREAD_GETATTR_NP) &&
+defined(HAVE_PTHREAD_ATTR_GETSTACK)
+	{
+		size_t size;
+		void *sstart;
+		pthread_attr_t attr;
+		pthread_getattr_np (pthread_self (), &attr);
+		pthread_attr_getstack (&attr, &sstart, &size);
+		/*g_print ("stackbottom pth is: %p\n", (char*)sstart + size);*/
+#ifdef __ia64__
+		/*
+		 * The calculation above doesn't seem to work on ia64, also we need
+to set
+		 * GC_register_stackbottom as well, but don't know how.
+		 */
+#else
+		GC_stackbottom = (char*)sstart + size;
+#endif
+	}
+
+rebuilt Mono, but the situation is the same :
+
+> mcs
+
+** ERROR **: file gc.c: line 138 (object_register_finalizer):
+assertion failed: (GC_base (obj) == (char*)obj - offset)
+aborting...
+Aborted
+
+By the moment, we have on machine:
