In module.cpp change

float **Module::getData(int index)
{
    if (!cycleReady) {
        generateCycle();
        cycleReady = true;
    }
    return data[index];
}

to

float **Module::getData(int index)
{
    if (!cycleReady) {
        cycleReady = true;
        generateCycle();
    }
    return data[index];
}

and recompile. If you have recent compilation tools you may
have to add -ldl to the list of libraries in Makefile.

The order of these two statements was apparently changed, 
but it *does* matter. If there is a loop, getData() for one
particular module will call itself before generateCycle()
returns. If that happens generateCycle() must not be called
again.
