c++: ICE during aggr CTAD for member tmpl [PR105476]
Here we're crashing from maybe_aggr_guide ultimately because
processing_template_decl isn't set when partially instantiating the
guide's parameter list; this causes us to force completion of the
dependent type Visitor_functior<Fn>, which of course fails and results
in an unexpected error_mark_node (the instantation should always succeed).
PR c++/105476
gcc/cp/ChangeLog:
* pt.cc (maybe_aggr_guide): Set processing_template_decl when
partially instantiating the guide's parameter list.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/class-deduction-aggr13.C: New test.
* g++.dg/cpp2a/class-deduction-aggr13a.C: New test.
