[R-pkg-devel] How to handle UBSAN false positives

Dear List,

in the last CRAN upload of my dqrng package I have enabled unit tests
for the C++ interface. Since then clang-UBSAN is listed under
"additional issues" on the CRAN check page [1]. I am fairly certain this
is a false positive, c.f. https://github.com/RcppCore/Rcpp/issues/832.

What would be best practice for handling this in the next upload?

1. Mention it in the upload comments as a false positive?
2. Disable the tests on CRAN?
3. Something else?

Thanks
Ralf
