Merge #1242
1242: Remove undefined behavior in context vector r=CohenArthur a=CohenArthur
This also fixes the undefined behavior. Once again we are hurt by
`std::vector<T>::back()` returning references and not
pointers/`std::optional<T>`s!
The cause of the bug was some overzealous popping from the context
vector in block expressions. The amount of calls to `pop_context` is now
the same as the amount of calls to `push_context`
Closes #1233
