Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Hi, since I observe what I believe is the same problem, I'd like to make 
this thread alive again. 
I tested installation from Fedora 25 repositories (cp2k version 3.0 
svn:16458) on 2 notebooks, one with kernel 4.8.16 (8GB ram, 2-core CPU), 
another with kernel 4.9.3 (20GB ram, 4-core cpu). On the one with kernel 
4.9.3 I compiled the trunk version 17688 as well (requirements installed 
from the repositories, see attached arch/Linux-x86-64-gfortran.popt 
makefile). Both openmpi and mpich versions result in the same behavior.
Some calculations run seemingly OK, but when I tried 
cp2k/tests/QS/regtest-hybrid-4 (or hybrid-2, I didn't try more) and try to 
run tests there I get:

Program received signal SIGSEGV: Segmentation fault - invalid memory 
reference.

Backtrace for this error:
#0  0x7fcddd807e3a
#1  0x7fcddd80702d
#2  0x7fcddccfb98f
#3  0x0


output file ends with:

Running the same test on our local cluster with trunk version 17176 goes 
fine. I can try to compile and run newer version on our cluster if that 
helps.
Any help is highly appreciated. Thank you
stano.
