Dear Maintainer, In Ubuntu, the attached patch fixes the FTBFS with OpenSSL 4.
Launchpad bug: https://bugs.launchpad.net/ubuntu/+source/identity4c/+bug/2154874 Thanks for considering the patch. - Brent Kerby
Description: Fix build with OpenSSL 4 by dropping removed cleanup API ERR_remove_thread_state() is deprecated since OpenSSL 1.1 and removed in OpenSSL 4. OpenSSL 1.1+ manages per-thread error state automatically, so this call is no longer needed.
