--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
It's seen on other targets too. Patrick came up with this reduced reproducer
for it:

--- a/gcc/testsuite/g++.dg/modules/pr106304_b.C
+++ b/gcc/testsuite/g++.dg/modules/pr106304_b.C
@@ -5,4 +5,5 @@ module pr106304;

 void f(A& a) {
   as_b(a);
+  dynamic_cast<B*>(&a);
 }

Just another latent front-end modules bug, that gets triggered by my new
library code.
