c++: ICE with header-units [PR 99071]
This ICE was caused by dereferencing the wrong pointer and not finding the
expected thing there. Pointers are like that.
PR c++/99071
gcc/cp/
* name-lookup.c (maybe_record_mergeable_decl): Deref the correct
pointer.
gcc/testsuite/
* g++.dg/modules/pr99071_a.H: New.
* g++.dg/modules/pr99071_b.H: New.
