Here enclosing_instantiation_of was failing to find a match because otctx is struct S<T> and current_function_decl is S<int>::S(), so the latter has more function contexts, and we end up trying to compare S() to NULL_TREE. After spending a bit of time working on establishing the correspondence in this case (class <=> constructor), it occurred to me that we could just use DECL_SOURCE_LOCATION, which is unique for lambdas, since they cannot be redeclared. Since we're so close to release, for now I'm only doing this for the case that was failing before. gcc/cp/ChangeLog: PR c++/95870 * pt.c (enclosing_instantiation_of): Compare DECL_SOURCE_LOCATION if there is no enclosing non-lambda function. gcc/testsuite/ChangeLog: PR c++/95870 * g++.dg/cpp0x/lambda/lambda-nsdmi10.C: New test.
