--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Marek Polacek <mpola...@gcc.gnu.org>: https://gcc.gnu.org/g:78cd6a63ee67ed854fbe54dd7c0a500dc138459a commit r11-5230-g78cd6a63ee67ed854fbe54dd7c0a500dc138459a Author: Marek Polacek <pola...@redhat.com> Date: Tue Nov 17 11:38:25 2020 -0500 c++: Allow template lambdas without lambda-declarator [PR97839] Our implementation of template lambdas incorrectly requires the optional lambda-declarator. This was probably required by an early draft of generic lambdas, but now the production is [expr.prim.lambda.general]: lambda-expression: lambda-introducer lambda-declarator [opt] compound-statement lambda-introducer < template-parameter-list > requires-clause [opt] lambda-declarator [opt] compound-statement Therefore, we should accept the following test. gcc/cp/ChangeLog: PR c++/97839 * parser.c (cp_parser_lambda_declarator_opt): Don't require (). gcc/testsuite/ChangeLog: PR c++/97839 * g++.dg/cpp2a/lambda-generic8.C: New test.
