[GitHub] [apr] ylavic commented on pull request #34: F ix a rare segfault in apr_global_mutex_child_init()

   apr_global_mutex_child_init() is not supposed to be called with `*mutex == NULL` (it should have been allocated with apr_global_mutex_create() first), so this is a usage/user error (i.e. don't do that)?
   Also, if something has to be done with the new `APR_ENOLOCK` error from this PR, it should be possible to do the same by testing `*mutex == NULL` before in the caller, so I don't get what this PR is fixing, looks like defensive programming only to me.
