re PR c++/77791 (ICE on invalid C++11 code with redefined function parameter: tree check: expected tree that contains ‘decl minimal’ structure, have ‘error_mark’ in cp_parser_lambda_declarator_opt, at cp/parser.c:1011)
PR c++/77791
* parser.c (cp_parser_lambda_declarator_opt): Only pedwarn
for C++11 on decls in the param_list. Test cxx_dialect < cxx14 before
the loop just once.
* g++.dg/cpp0x/lambda/lambda-77791.C: New test.
