Firstly, issuing a warning for a compiler-generated expression is wrong and secondly, B && true must be wrapped in ( ) otherwise you'll get error: binary expression in operand of fold-expression. PR c++/94505 - bogus -Wparentheses warning with fold-expression. * pt.c (fold_expression): Add warning_sentinel for -Wparentheses before calling build_x_binary_op. * g++.dg/cpp1z/fold11.C: New test.
