'orderder_queue.hpp' defines ORDER_QUEUE_XPXC(MPSC with the additional wait condition (num - target.last_tenant <= this->queue_size).
num is uint64_t and the rest of the variables are size_t. target.last_tenant is initialised to -1. On 64 bit architectures this condition evaluates to true due to the integer overflow. On 32 bit architectures size_t is 32 bits and overflow does not happen, resulting in always false wait condition.
The causes the queue to wait indefinitely and self-tests to fail [1].
