Yup: scheduling the pass after ubsan fixes it, scheduling is before ICEs as
well. So either simply that, or something like
--- a/gcc/passes.def
+++ b/gcc/passes.def
@@ -57,6 +57,9 @@ along with GCC; see the file COPYING3. If not see

(Maybe that PUSH_INSERT_PASSES_WITHIN makes it cheaper for non-ubsan
compilation?)
