With valgrind I obtained this output:
Process terminating with default action of signal 11 (SIGSEGV): dumping core

It seems the issue is inside an “outdated” version of libnode.so. I just copied another version of libnode.so from the latest atom.rpm installation with:
sudo mv /usr/lib/slack/libnode.so /usr/lib/slack/libnode.so.old
sudo ln -s /usr/share/atom/libnode.so /usr/lib/slack/libnode.so
Edit
Like user Pierre Bellan already said, you can easily find other version of libnode.so on your OS with:
sudo updatedb && locate libnode
I used the atom one because I was sure about a recent working update of the editor.
