c++: attribute on dtor in template [PR108795]
Since r7-2549 we were throwing away the explicit C:: when we found that ~C
has an attribute that we treat as making its type dependent.
PR c++/108795
gcc/cp/ChangeLog:
* semantics.cc (finish_id_expression_1): Check scope before
returning id_expression.
gcc/testsuite/ChangeLog:
* g++.dg/ext/attr-tsafe1.C: New test.
