Bug ID: 101482
Summary: The resolution of #32907 is too restricted
Product: gcc
Version: 11.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: de34 at live dot cn
Target Milestone: ---
The resolution of bug #32907 is restricted to a few specializations
(basic_string<CharT>, where bool(__is_char<CharT>::value) is true).
It seems that the resolution should be generalized to all specializations of
basic_string (by removing the legacy operator== overload and SFINAE in the new
overload, which is already done by libc++ and msvc stl). IMO the generalized
resolution can also be applied to operator== for __versa_string.
