[Rd] Advice on ASAN for gap 1.9

[jinghua zhao]

Dear R developers,

I am seeking advice regarding some issues of my package from CRAN check. I have made attempts to identify sources of the errors via customized clang/gcc which may not always yield the same errors. I also tried ~/.valgrindrc and --use-valgrind which would say OK but I suspect my ASAN-scheme is fully working. Brefly, the error tracking information can be seen from here,

  *
CRAN checks, https://cran.r-project.org/web/checks/check_results_gap.html
  *
Current attempt. https://cran.dev/gap

For next steps, I wonder if

  *
Anyone has a polished pipelines clang/gcc for Fedora 43  which is what I am using so as to reproduce errors / hints for any additional changes to be made, e.g., https://www.stats.ox.ac.uk/pub/bdr/Rconfig/
  *
To convert the somewhat legacy C/Fortran codes in the package for more modern implementations.

More importantly, any advices will be greatly appreciated.

Best wishes,

Jing Hua
