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.
