<div>
<pre>Code that calls a function like:
template <int ID>
__attribute__(( const ))
SomeClass const & someFunction()
{
static SomeClass const someObject( ID );
return someObject;
}
miscompiles with all versions of Clang shipped with Xcode after version 4.2.
Removing the const function attribute makes the bug disappear. Is this a Clang
bug or am I misunderstanding the semantics and requirements of the const
function attribute?</pre>
