Re: What are all these core files?

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

Yes, those are core files related to various "xscreensaver" display
modes (/usr/pkg/libexec/xscreensaver/*).

If you have "xscreensaver-demo" installed, you might be able to see what
happens when those modes are selected to run.

In the thread starting with:

  http://mail-index.netbsd.org/pkgsrc-users/2018/07/02/msg027089.html

I noted problems with image loading which would cause several display
modes ("display hacks") to segfault.  That much was fixed in pkgsrc-HEAD,
but the 'xscreensaver-getimage' helper program still dumps core when it
should be supplying a colorbar image.
