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