And because rax was zero, the effective read address was 0x440. According memory mapping list, zeroth page was unmapped. Thus it's simple NULL pointer dereference in libgtk2++. I will check _gdk_x11_screen_process_owner_change() code in gdkscreen-x11.c later. -- Configure bugmail: https://bugzilla.redhat.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. -- Fedora Extras Perl SIG http://www.fedoraproject.org/wiki/Extras/SIGs/Perl perl-devel mailing list perl-devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/perl-devel
