// The program crashed with segfault because we when we first compile foo
// and bar we allocate all four variables (a, b, c and d) to the context.
// When we compile foo the second time (with optimizations) we allocate
// only c and d to the context. This happened because parser folds away
// "${a}" and "${b}" as constant expressions when parsing bar on its own,
// i.e. the expressions were not parsed again and thus a and b were not
// marked as captured.
// This caused a mismatch between a context that bar expects and that
// the optimized version of foo produces.
