Bug ID: 38604
Summary: std::string is too eager in
convertibility-to-string_view checks
Product: libc++
Version: unspecified
Hardware: All
OS: All

libc++-style test case
Since https://reviews.llvm.org/D48616, we’re checking
convertibility-to-string_view in several std::string methods. However, those
new templated methods are not guarded behind C++17 checks, which means that
we’re still making those checks in C++11 and C++14. This is bad for types that
provide promiscuous conversion operators, as they can sniff that we're
providing these methods in C++11/C++14. This breaks conforming (but misbehaved)
code. I attached a test case that currently fails.
