backtrace and two core files
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()
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 ?
fixed as of FC5. sorry I didn't get back to this to test it. thanks for the
even if I point it at ~/Pictures now, which has some huge files in it, there
are no coredumps.
