<pre>Yes, this was fixed in r312818. PR36086 is unrelated; it's an issue in clang.
The clang frontend is able to constant-fold away some expressions and when this
happens, the effect of the expression is not always reflected in the coverage
mapping. In some cases this can be fixed by emitting counter updates even when
an expression is constant-folded. I'm not sure what would be required to
support constexpr.</pre>
