BTW, the failing test still fails if I
- keep ",pointer-compare,pointer-subtract" in '-fsanitize=...'; yet
- set 'detect_invalid_pointer_pairs=0' in $ASAN_OPTIONS
IOW, the 'pointer-whatever' options prevent linking 'zero_test' even
if the environment variable attempts to nullify them. Linker error:
/usr/bin/ld: zero_test.o: in function `std::__cxx11::basic_stringbuf<char,
std::char_traits<char>, std::allocator<char> >::str() const &':
