Problem: Date and time functions - `STR_TO_DATE` and `TO_DATE` (in Oracle mode) both use `check_word` to check if a string token matches a valid locale-specific day or month name. Server crashed because of an un-initialized typelib member(`type_lengths`) for date locales which are not present in `Oracle_date_locale` (e.g: `ar_DZ`). Fix: Initialize `type_lengths` for all supported locales by iterating over `my_locales` array instead of `Oracle_date_locale` during server startup.
