Segmentation fault (core dumped)

[jasmin]

when install Nodejs, and run "node -v" i get this error "Segmentation fault"

when I try to install a new package with "npm" I got this error too "Segmentation fault (core dumped)"

I've tried most of the helps I've found the internent.. but nothing works.
Is there any best solution you may give me...?
