The deprecated non-standard std::pair constructors that allow constructing std::pair<move-only-type, pointer-type> from an rvalue and a literal zero where not sufficiently constrained. They were viable when constructing std::pair<copyable-type, pointer-type>, and that case should work fine using the standard constructors. Replace the constraints on the non-standard constructors so they are only viable in cases that should actually be ill-formed according to the standard. Also rename __null_ptr_constant to __zero_as_null_pointer_constant so it matches the name of the -Wzero-as-null-pointer-constant warning. Also make the text of the deprecated warning describe the problem in more detail. libstdc++-v3/ChangeLog: PR libstdc++/101124 * include/bits/stl_pair.h (pair): Adjust constraints on deprecated constructors accepting literal zero as null pointer constant. Improve wording of deprecated attribute. * testsuite/20_util/pair/cons/99957.cc: Check that deprecated constructors do not cause ambiguities for copyable types. |
