My understanding:

COMMON_INTERCEPTOR_INITIALIZE_RANGE is only defined for msan.

- asan re-defines COMMON_INTERCEPTOR_WRITE_RANGE (the buffer is specified by the user - the addressability needs to be checked) but not COMMON_INTERCEPTOR_INITIALIZE_RANGE (static storage is known to be *addressable* so there is no need to check addressability).
- tsan re-defines COMMON_INTERCEPTOR_WRITE_RANGE (the buffer is specified by the user - the potential data race needs to be checked) but not COMMON_INTERCEPTOR_INITIALIZE_RANGE (data race will not be checked - potential false negatives).
