Hi, there is SIGSEGV happens in qconf.cc:995
str += print_filter(sym->name);
but sym points to 0x1. To reproduce the error just do:
1) make xconfig (with Options->Show Debug Info unchecked) 2) go to Networking->Networking Options->Network packet filtering framework (Netfilter)-> Network packet filtering framework (Netfilter) and the line "<| .." must be selected then just turn on Options->Show Debug info menu and you'll get:
make[1]: *** [xconfig] Segmentation fault make: *** [xconfig] Error 2
gdb shows:
Program received signal SIGSEGV, Segmentation fault. 0x08069834 in ConfigInfoView::symbolInfo (this=0x85ae750) at qconf.cc:995 (gdb) bt #0 0x08069834 in ConfigInfoView::symbolInfo (this=0x85ae750) at qconf.cc:995 #1 0x080696a9 in ConfigInfoView::setShowDebug (this=0x85ae750, b=true) at qconf.cc:946 #2 0x080648bf in ConfigInfoView::qt_invoke (this=0x85ae750, _id=161, _o=0xbfc56ea0) at qconf.moc:544 #3 0xb7a5b1cc in QObject::activate_signal () from /usr/qt/3/lib/libqt-mt.so.3 #4 0xb7a5b800 in QObject::activate_signal_bool () from /usr/qt/3/lib/libqt-mt.so.3 #5 0xb7dbd44b in QAction::toggled () from /usr/qt/3/lib/libqt-mt.so.3 #6 0xb7ba0876 in QAction::setOn () from /usr/qt/3/lib/libqt-mt.so.3 #7 0xb7ba0a94 in QAction::internalActivation () from /usr/qt/3/lib/libqt-mt.so.3 #8 0xb7dbd544 in QAction::qt_invoke () from /usr/qt/3/lib/libqt-mt.so.3 #9 0xb7a5b1cc in QObject::activate_signal () from /usr/qt/3/lib/libqt-mt.so.3 #10 0xb7d9cc7a in QSignal::signal () from /usr/qt/3/lib/libqt-mt.so.3 #11 0xb7a753bd in QSignal::activate () from /usr/qt/3/lib/libqt-mt.so.3 #12 0xb7b62c09 in QPopupMenu::mouseReleaseEvent () from /usr/qt/3/lib/libqt-mt.so.3 #13 0xb7a915b7 in QWidget::event () from /usr/qt/3/lib/libqt-mt.so.3 #14 0xb79fe9df in QApplication::internalNotify () from /usr/qt/3/lib/libqt-mt.so.3 #15 0xb79fde44 in QApplication::notify () from /usr/qt/3/lib/libqt-mt.so.3 #16 0xb79937c1 in QETWidget::translateMouseEvent () from /usr/qt/3/lib/libqt-mt.so.3 #17 0xb7991835 in QApplication::x11ProcessEvent () from /usr/qt/3/lib/libqt-mt.so.3 #18 0xb79a8bb4 in QEventLoop::processEvents () from /usr/qt/3/lib/libqt-mt.so.3 #19 0xb7a10d18 in QEventLoop::enterLoop () from /usr/qt/3/lib/libqt-mt.so.3 #20 0xb7a10bc8 in QEventLoop::exec () from /usr/qt/3/lib/libqt-mt.so.3 #21 0xb79fec31 in QApplication::exec () from /usr/qt/3/lib/libqt-mt.so.3 #22 0x08074453 in main (ac=2, av=0xbfc57ac4) at qconf.cc:1736 (gdb) p sym $20 = (symbol *) 0x1
