https://www.ibm.com/docs/en/aix/7.3?topic=p-pthread-once-init-macro
https://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_once.html

"The behavior of pthread_once() is undefined if once_control has
automatic storage duration or is not initialized by PTHREAD_ONCE_INIT."

You can initialize just about anything with PTHREAD_ONCE_INIT, but you
cannot expect the resulting structure to work as intended if there is
more than instance per library / program, so the libstdc++ object should
be a singleton, not automatic.

Still looks like ATWIL to me…
