Maybe we could add calls to e.g. __asan_check_abi_mismatch(uptr a1, uptr a2, uptr a3, uptr a4, uptr a5, uptr a6) after every call to __asan_init (a1 == offset, a2 == shift, a3 == something_else, etc) if any of a1..a6 is different between the calls to __asan_check_abi_mismatch -- fire an error. WDYT?
