Description
We allocate memory in boostrapped or non-double-conversion builds because we copy the input data to make it NUL-terminated for consumption by sscanf. Apart from being extremely inefficient, making parsing a sequence of doubles from a string quadratic, it also prevents functions from becoming noexcept.
