Bug ID: 359685
Summary: Kate SEGSIGV when trying to load the project plugin
Product: kate
Version: Git
Platform: Gentoo Packages
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: elv1...@gmail.com
I just upgraded my Gentoo system (latest GLibc, GCC) and Kate now crash on
load.
This is due to the plugin system failing to load the project plugin. I looked
around and no left-over file seem to be present. For now, I patched it using
void KatePluginManager::loadPlugin(KatePluginInfo *item)
{
/**
* try to load the plugin
*/
if (item->saveName() != QLatin1String("kateprojectplugin"))
item->load = (item->plugin =
KPluginLoader(item->metaData.fileName()).factory()->create<KTextEditor::Plugin>(this,
QVariantList() << item->saveName()));
/**
* tell the world about the success
*/
if (item->plugin) {
emit KateApp::self()->wrapper()->pluginCreated(item->saveName(),
item->plugin);
}
}
Reproducible: Always
Steps to Reproduce:
1. Open Kate
Actual Results:
segmentation fault
Expected Results:
All plugins being loaded
CXXFLAGS="-fsanitize=undefined -fsanitize=address -fsanitize=leak -ggdb -O0"
make -j && kate
kate: Last session is: ""
