Mark says things are in and Ondrej offered its help so I resume my old idea to use gcc/g++ sanitizers with Kea.

Summary of findings in jenkins settings:

  • there is a hack to not remove atf.out IMHO very specific
  • -fsanitize=xxx (one each time) in CFLAGS and LDFLAGS in ./configure command line
  • make -k check (-k == keep-going)
  • aft-report from atf.out (again very specific)

Summary from Clang doc (sanitizers are available with Clang too, shall check soon with macOS and Xcode):

  • use -fno-omit-frame-pointer for better reports
  • do not use ld but clang or gcc driver (check what libtool does but it should be good)
  • some macOS specific stuff (so should try on Linux first),

Summary from gcc doc:

  • available address (with pointer-compare and pointer-subtract options), thread, leak, undefined (with options)
  • also -fsanitize-address-use-after-scope (there is at least in the asio code so it will be useful...)
