[R-pkg-devel] UBSAN Problems with Memory Sanitizer
Ok thanks Dirk! I'll try to explain to the CRAN team. Yes the vignette-issue because of duplicated file titles is solved. Best, Max

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? Dirk -- http://dirk.eddelbuettel.com | @eddelbuettel | edd at debian.org
