 This function calls the rightsize_buf function, which attempts to
 reallocate a buffer if there isn't enough space.  It is possible, but
 extremely unlikely, that the reallocation will fail and the buffer will be
 replaced with a nullptr.  Any attempt to dereference that nullptr will
 crash the frontend.
