Rock, meet hard place. It seems you are getting an UBSAN error from an
external library. That can happen, and sometimes you get to explain it to
CRAN so that the package gets admitted.

Having glanced at the output below the page at
  https://cloud.r-project.org/web/checks/check_results_IncDTW.html
I think there is little you can do on your end about the UBSAN issues.

I presume you did your part to make the NOTE from the vignette disappear?
