looking back, we had the same issuein 2020...

The solution proposed by ROmain was to comment out this code:

int CRYPTO_atomic_add(int *val, int amount, int *ret, CRYPTO_RWLOCK *lock)
{
#if 0
# if defined(__GNUC__) && defined(__ATOMIC_ACQ_REL)
    if (__atomic_is_lock_free(sizeof(*val), val)) {
        *ret = __atomic_add_fetch(val, amount, __ATOMIC_ACQ_REL);
        return 1;
    }
# endif
#endif
