            Bug ID: 22951
           Summary: -std=c++14 causes link failure due to missing operator
                    delete(void*, unsigned long)
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P

    Classification: Unclassified

As reported to me via MacPorts trac, recent trunk fails to include a static
implementation of operator delete(void*, unsigned long) and thus fails to link
when using --std=c++14

$ cat foo.cc
int main()
{
  auto f = new int;
  delete f;
}
$ clang++-mp-3.6 -std=c++14 foo.cc
$ clang++-mp-3.7 -std=c++14 foo.cc
Undefined symbols for architecture x86_64:
  "operator delete(void*, unsigned long)", referenced from:
      _main in foo-7bc325.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
