freelocale woes

  Don't call freelocale on a locale
  that was the base of a successful newlocale, as that
  results in a double free.

On which system was this? I'm asking because

  - In the glibc implementation (freelocale and _nl_remove_locale),
    I can see that shared data between locales is protected by usage counts.

  - glibc hasn't changed in this area since 2009.

  - If freelocale() really is transitive, how would a programmer proceed
    if he has dependencies between locale objects

              A  -->  C
              B  -->  C

    and he wants to free B but keep A ?
