We are seeing this in Fedora 25 based on glibc 2.24, and it is impacting
kerberos authentication for ssh.

    Bug 11941: ld.so: Improper assert map->l_init_called in dlclose
    
    There is at least one use case where during exit a library destructor
    might call dlclose() on a valid handle and have it fail with an
    assertion. We must allow this case, it is a valid handle, and dlclose()
    should not fail with an assert. In the future we might be able to return
    an error that the dlclose() could not be completed because the opened
    library has already been unloaded and destructors have run as part of
    exit processing.
