// We had an off-by-one error in an assertion when annotating A<int> below. Our
// error recovery checks if A<int> is a constructor declarator, and opens a
// TentativeParsingAction. Then we attempt to annotate the token at the exact
// position that we want to possibly backtrack to, and this used to crash.
