+	  if (!id->debug_stmts)
+	    id->debug_stmts = VEC_alloc (gimple, heap, 1);
+	  VEC_safe_push (gimple, heap, id->debug_stmts, copy);


Note that VEC_safe_push will also handle the initial
allocation of the VEC from NULL.  It's quite handy.

Which means that

   if (MAY_HAVE_DEBUG_STMTS)
-    VARRAY_GENERIC_PTR_INIT (id.debug_stmts, 8, "debug_stmt");
+    id.debug_stmts = VEC_alloc (gimple, heap, 0);

probably only needs to be

id.debug_stmts = NULL;
