There is a shorter sequence:

c++: Fix unhiding friend with imports [PR 99248]
This was a simple thinko about which object held the reference to the
binding vector. I also noticed stale code in the tree dumper, as I
recently removed the flags from a lazy number.
PR c++/99248
gcc/cp/
* name-lookup.c (lookup_elaborated_type_1): Access slot not bind
when there's a binding vector.
* ptree.c (cxx_print_xnode): Lazy flags are no longer a thing.
gcc/testsuite/
* g++.dg/modules/pr99248.h: New.
* g++.dg/modules/pr99248_a.H: New.
* g++.dg/modules/pr99248_b.H: New.
