+Subject: [PATCH 2/2] libstdc++: fix incomplete type in
+ v8::internal::is_subtype<T, U>
+
+Using std::convertible with incomplete types is UB. However, till
+GCC 12 it was accepted and std::convertible returned false.
+This fails now for e.g. v8::internal::WasmArray. Use
+std::disjunction and std::conjunction instead which are short-
+circuiting, because std::is_base_of<T, T> is already true.
