Bug ID: 30303
Summary: error: no matching function for call to
'__ptr_in_range'
Product: libc++
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: All Bugs

The following code used to compile, but now fails as below. This is reduced
from some code in Chromium.
#include <string>
#include <vector>
#include <cstdint>
using namespace std;
void f(string &s, vector<uint8_t> &v) {
s.append(v.begin(), v.end());
}

Fix Bug 30240 - std::string: append(first, last) error when aliasing. Add test
cases for append/insert/assign/replace while we're at it, and fix a similar bug
in insert.
