When the lambda's generic but the containing function is not a temploid, we'll never have tsubsted the declaring decl so won't have a local specialization. But in that case we can just use the decl we tsubsting directly -- it's not dependent. PR c++/99030 gcc/cp * pt.c (tsubst_copy) [VAR_DECL]: For a DECL_LOCAL_DECL_P T is the answer if there's no local specialization. gcc/testsuite/ * g++.dg/lookup/pr99030.C: New.
