So make sure to look into {} too. We don't need to handle nested {} here. We could either tweak resolve_nondeduced_context to handle CONSTRUCTORs or add a _ctor version, but then resolve_nondeduced_context_or_error would need some changes too -- it'd have to check the result of a call to r_n_c for each element. gcc/cp/ChangeLog: PR c++/93107 * pt.c (do_auto_deduction): Call resolve_nondeduced_context for the elements of a { } list. gcc/testsuite/ChangeLog: PR c++/93107 * g++.dg/cpp0x/initlist-deduce3.C: New test. ^ permalink raw reply [flat|nested] 4+ messages in thread
