In https://sourceware.org/ml/libc-alpha/2014-12/msg00300.html, we give a "called from here" note without actually having a location, which looks strange. I haven't been able to generate such a testcase. In this patch, we assert this cannot happen when checking and simply skip the extra note in release mode.
