19 // 1) initialized with default values at startup.
20 // 2) overriden during compilation of ASan runtime by providing
21 // compile definition ASAN_DEFAULT_OPTIONS.
22 // 3) overriden from string returned by user-specified function
23 // __asan_default_options().
24 // 4) overriden from env variable ASAN_OPTIONS.
