The error here should also check that we aren't nested in another
lambda; in it, at_function_scope_p() will be false.
PR c++/117602
gcc/cp/ChangeLog:
* parser.cc (cp_parser_lambda_introducer): Check if we're in a lambda
before emitting the error about a non-local lambda with
a capture-default.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/lambda-uneval19.C: New test.

How about using current_nonlambda_scope () instead of
at_function_scope_p ()?
