In fact, while Optimiser.py states that this value defaults to True, it is often 0.
I've also seen consider_empty_communities evaluate to 32732 and 1081192448 (among many other "True" values), depending on whatever happened to reside in memory at the time.
A fix is to simply set this->consider_empty_community = true; in the Optimiser constructor (if defaulting to True is indeed intended).
For what it's worth, the valgrind error that initially alerted us to this problem (while writing #34) is as follows:
Optimiser::consider_empty_communities is never initialized (unless Optimiser.consider_empty_community is explicitly set from Python).
Hence, the if statement on line 402 of Optimiser.cpp is undefined behavior.
