[R-pkg-devel] Reproducing the clang-UBSAN test environment in rhub or somewhere else?

[Peter Carbonetto]

Hi All,

A recent update to my package has generated an unexpected error in the
clang-UBSAN test environment (as well as gcc-UBSAN):
https://cran.r-project.org/web/checks/check_results_fastTopics.html

However, I could not reproduce this error using rhub (platform =
"gcc-ubsan"), which makes it difficult to troubleshoot (and eventually
correct) this error.

Does anyone have suggestions for how I could reproduce the error (rhub or
otherwise), or is there more detailed documentation somewhere on the
clang-UBSAN environment? I'm at a bit of a loss for how to proceed.

Thank you,
