  20 // 1) initialized with default values at startup.
  21 // 2) overriden during compilation of ASan runtime by providing
  22 //    compile definition ASAN_DEFAULT_OPTIONS.
  23 // 3) overriden from string returned by user-specified function
  24 //    __asan_default_options().
  25 // 4) overriden from env variable ASAN_OPTIONS.
  26 // 5) overriden during ASan activation (for now used on Android only).
