address sanitizer fails with this error upon starting the DU:

  SUMMARY: AddressSanitizer: odr-violation: global 'log_mem_write_side' at /oai-ran/common/utils/LOG/log.c:78:14

So we do as suggested and disable ODR violations to make the test pass.
A proper solution would be to link this function only once.
