However, there's noresponse from GCC devs since we have raised the issue for several weeks.In this case, I think we can disallow statement expressions as a defaultparameter in general for now, and relax the restriction if GCC folksdecide to retain the feature for functions but not lambdas in thefuture.Related discussion: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104765Fixes https://github.com/llvm/llvm-project/issues/53488Differential Revision: https://reviews.llvm.org/D119609 List of files: /llvm-project-15.0.7/clang/test/Sema/stmt-expr-in-default-arg.cpp Wed, 06 Apr 2022 00:45:46 +0000 Jun Zhang <jun@junz.org>
