asan_set_error_report_callback is closer to what you need but
  1. it's only available in asan (well, this *may* need to be fixed separately)
  2. it has the same problem: what if someone else want to call it to. I'e. it will need to be chained.
  3. You say it does not work. Strange. Will need more info separately. 

Does __sanitizer_set_report_path do (almost) what you need?
