Dear all, I have been asked to fix a UBSAN error in my dqrng package. The error itself and the necessary fix are quite straight forward. However, I want to make 100% sure that I am really fixing the error. In the past I had used rhub for tasks like that. But it seems like the new rhub v2 offers only ASAN testing. I have also tried various docker images (wch1/r-debug, old rhub images, rocker), but with none of them I was able to reproduce the error seen on CRAN. What would you consider as "state of the art" for reproducing UBSAN errors? Thanks Ralf
[R-pkg-devel] State of the art for UBSAN testing
3 messages · Ralf Stubner, Gábor Csárdi
R-hub v2 has UBSAN testing, the clang-asan image also has UBSAN. [1] With the glitch that UBSAN errors do not fail the build because of a bug [2], so you'll need to look at the results even if the build has passed.

Thanks G?bor! If one checks the output, one can indeed find the UBSAN error. Problem solved! Ralf
