  Log Message:
  -----------
  Fix out-of-bounds access to std::unique_ptr<T[]> (#111581)

This manifested as an assertion failure in Clang built against libc++
with
hardening enabled (e.g.
-D_LIBCPP_HARDENING_MODE=_LIBCPP_HARDENING_MODE_DEBUG):
`libcxx/include/__memory/unique_ptr.h:596: assertion
__checker_.__in_bounds(std::__to_address(__ptr_), __i) failed:
unique_ptr<T[]>::operator[](index): index out of range`
