[CP2K:1839] segmentation fault on a water example

[Teodoro Laino]

Hi Marius,

I can't find any problem (with valgrind) on that specific input. It 
could easily be some problem with the intel compiler you used. Did you 
try another one?
or did you try to switch off all optimization levels? change libraries? 
stay on 1 foot while compiling?
