Instead of putting it inside an assertion, how about adding a check for FunctionParmPackExpr separately? I mean, ```cpp if (auto *Expr = dyn_cast<FunctionParmPackExpr>(E); Expr && getEnclosingLambda()) return false; ``` to bail out only inside the `Expr` overload of `DiagnoseUnexpandedParameterPack`. (since it's the one being called anyways during template instantiation.) https://github.com/llvm/llvm-project/pull/69224 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
