If you build against g++-5 (or look up old build logs on buildd.d.o), 
you get a helpful warning for this line:

HYChartWindow.cpp:3010:54: warning: converting 'false' to pointer type for argument 3 of '_Formula::_Formula(_String&, _VariableContainer*, _String*)' [-Wconversion-null]
                     _Formula f (*thisString,nil,false);
                                                      ^

This code relied on automatic conversion from "false" to null pointer, 
which was always a dubious feature, and now no longer works in GCC 6. 
Changing "false" to "nil" should fix this.
