Hi folks,
I'm the maintainer of the redist package
(https://cran.r-project.org/web/checks/check_results_redist.html) which was
flagged for additional issues with clang-UBSAN and gcc-UBSAN. Both of the
00check.log files say that the status is "OK" at the bottom.
Is there an easy way to identify what is causing the flag? I see things that it
could be, for example in the tests Rout files, there are sanitizer errors like:
wilson.cpp:165:34: runtime error: signed integer overflow: -2147483648 * -1
cannot be represented in type 'int'
However, my understanding is that these errors should be expected, as the input
is controlled from within the package and checking for these types of errors in
every loop would push against the purpose of using C++ for performance here.
That leads me to believe that either I'm looking past the seriousness of one of
these sanitizer warnings or I am missing something else that is being flagged.
I've looked at Writing R Extensions part 4.3, but do not see any specific
additional information on this. Does anyone have advice or any guidance on
figuring out exactly what causes the "Additional Issues" flag and subsequent
email about fixing it?
Thank you,
Chris
