// ASan flag values can be defined in four ways:
// 1) initialized with default values at startup.
// 2) overriden during compilation of ASan runtime by providing
// compile definition ASAN_DEFAULT_OPTIONS.
// 3) overriden from string returned by user-specified function
// __asan_default_options().
// 4) overriden from env variable ASAN_OPTIONS.
// 5) overriden during ASan activation (for now used on Android only).
