Segmentation fault bug in hybrid functional HFX calculations

Hi Matt,

yes, in the final computations the EPS_SCHWARZ of course has to be much 
smaller. In fact, I just provided a small test case showing the 
segmentation fault bug as fast as possible.
For my large system, I still get the segmentation fault for EPS_SCHWARZ 
1.0E-4, which, of course, is still quite unprecise, but, as you say, the 
error disappears for EPS_SCHWARZ <= 1.0E-6.
In fact, I initially set EPS_SCHWARZ higher in order to test other 
parameters quickly, and then wanted to decrease EPS_SCHWARZ finally after 
fixing other parameters. That's how the bug showed up initially.
Well, I will try to continue for now like that and hope the bug doesn't 
show up any more.

Thanks for the suggestions.
