you can check this, if you want to suppress this leak. https://github.com/google/sanitizers/wiki/AddressSanitizerLeakSanitizer#suppressions

More, you can also specify the suppression list at source code level:

extern "C"
const char *__lsan_default_suppressions() {
  return "leak:*LSanTestLeakingFunc*";
}
