npviewer.bin exited on signal 6 (core dumped) with www/linux-flashplayer

I don't know whether it's specific to www/linux-flashplayer, but whenever the plug-in loads (in Waterfox or Firefox) there's a dump.

This morning, for example (from dmesg, after a few visits to <https://helpx.adobe.com/flash-player.html>):

pid 34576 (npviewer.bin), uid 1004: exited on signal 6 (core dumped)
pid 35395 (npviewer.bin), uid 1004: exited on signal 6 (core dumped)
pid 36304 (npviewer.bin), uid 1004: exited on signal 6 (core dumped)
pid 36316 (npviewer.bin), uid 1004: exited on signal 6 (core dumped)
pid 36359 (npviewer.bin), uid 1004: exited on signal 6 (core dumped)
pid 36371 (npviewer.bin), uid 1004: exited on signal 6 (core dumped)
pid 36401 (npviewer.bin), uid 1004: exited on signal 6 (core dumped)
pid 36414 (npviewer.bin), uid 1004: exited on signal 6 (core dumped)
pid 36446 (npviewer.bin), uid 1004: exited on signal 6 (core dumped)
pid 36459 (npviewer.bin), uid 1004: exited on signal 6 (core dumped)

Should I raise a bug against www/linux-flashplayer, or against something else?

For one of the exits, with Firefox run in safe mode at the command line:
