<pre>This invalid input crashes "clang++ -c input.cpp":
template <T> f() { class ClassA class : ClassB, ClassA
It is necessary for "ClassA" and "ClassB" names to be similar enough to trigger
the typo suggestion and the crash. This affects all versions of Clang, from
3.7 to trunk (r344434).
This bug is different from <a class="bz_bug_link
