Created attachment 128879 [details] Patch to prevent double free in demo-Gtk.c I don't have FC4 system any more and so I cannot make use of core file. But by checking xscreensaver-backtrace.txt in the attachment in the comment 1, it is found that this is a problem of double-free in run_hack() in demo-Gtk.c A patch is attached to fix this problem. Note: this problem is already fixed in version 4.24.
This report targets the FC3 or FC4 products, which have now been EOL'd. Could you please check that it still applies to a current Fedora release, and either update the target product or close it ? Thanks.
fixed as of FC5. sorry I didn't get back to this to test it. thanks for the reminder. even if I point it at ~/Pictures now, which has some huge files in it, there are no coredumps.
