Bug ID: 61374
Summary: string_view::operator string() is buggy
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: john.salmon at deshaw dot com
The problem is the string(length, c) constructor on line 255 of string_view.
The begin/end constructor is what's needed. Here's a quick demonstration.
drdlogin0039$ cat bug.cpp
#include <experimental/string_view>
#include <string>
std::experimental::string_view sv("hello world");
std::string s {sv};
drdlogin0039$
