Stacking pdf layers: MWE breaks linux pdf viewers okular and evince

Question

I would have commented on Stacking pdf layers But lacking the reputation, I'll have to open a new thread.

However

That is the provided MWE in said thread. pdflatex executed twice creates a pdf that - on click on any of the links - crashes okular and evince. Can someone reproduce that? Or is that a local thing?

Edit: evince tells something
