Segmentation fault with gcc 7.2.0

[Anton Kudelin]

Dear Alfio,

I've found the point of the error. It is caused by libint linked 
dynamically, in the case of the static library segmentation fault is not 
being observed. It's a weird behaviour, but not critical. The psmp version 
passed all tests without errors.
Thank you very much for help!

Best Regards,
Anton K.
