Two issues here: - Checking table size to be non-zero is not a proper way to go here. This is because we first resize the table and then fill it in. So it was possible that non-initialized table was used. Trickery with using temporary memory and then doing table.swap() might work, but we can not guarantee that table size will be set after the data pointer. - Mutex guard was useless, because every thread was using own mutex. Need to make mutex guard static so all threads are using same mutex.
