<pre>c_str is defined as force-inline, which causes the compiler to not emit it in
any translation unit. It is not included in libc++.dylib either. Taking the
address causes an undefined symbol to be emitted regardless, but the compiler
does not include the implementation.
As far as I can tell the compiler should emit the symbol if it is explicitly
used, even if it is marked as force-inline.</pre>
