<div>One of my colleagues pointed this issue out to me a while back too. I took a quick look but wasn't able to figure out why the warning isn't being suppressed (I'm not particularly familiar with clang). I opened <a href="http://llvm.org/bugs/show_bug.cgi?id=8129">http://llvm.org/bugs/show_bug.cgi?id=8129</a> to track the issue.</div></div></blockquote><div><br></div><div>It's not being suppressed because the diagnostic is triggering at an invalid location. That's why the warning doesn't have line/column information or a caret display. We're probably just not preserving information correctly into template instantiation in this case.</div><div><br></div><div>John.</div></div></body></html>
