<div>
<pre>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)</pre>
