[CP2K:2663] Memory leak on Mare Nostrum

Ciao Marco,

This is probably a bug in the compiler: when you allocate ALLOCATABLE 
you can avoid to release them since the compiler should automatically 
deallocate them when leaving the subroutine. In any case, I remember 
quite well that few of these problems were fixed in the last 2 years 
(i.e. each allocatable after being allocated was followed by a 
deallocate at the end of the subroutine). Probably, other allocation 
(not followed by deallocation) have been introduced since then.
We can try to find/fix them but in order to do so I need to know 
precisely if you checked this behavior with an up-to-date cp2k version.

Cheers,
Teo
