--- Comment #2 from Kaelyn Takata <rikka at google.com> ---
Indeed it was fallout in the form of a code path not covered by any of the
regression tests where a type-dependent TypoExpr node would be seen by a
non-C++ code path that tried to check the expression's type and failed. I've
fixed this case and added a test in r222694.

As an aside, the assertion in ~Sema from r222552 would have been triggered if
asserts were enable, highlighting the fact that a typo had been encountered but
never corrected (i.e. a TypoExpr was created but never diagnosed) and providing
a better indication of what went wrong than the generated error message had. ;)
