Bug 147106 – [GTK] SIGABRT in WebKitWebProcess WebKitGtk+ 2.8.4 and 2.10.x when visiting some pages on dispatchDecidePolicyForNavigationAction

• Component: WebKitGTK
• Status: NEW

[Andres Gomez Garcia]

I'm using WebKitGtk+ with my own JHBuild setting:
https://github.com/tanty/jhbuild-epiphany/tree/wkgtk-devel

Epiphany 3.17.1 and WebKit 2.8.4

I'm running Epiphany with the dconf key:

"process-model" = "shared-secondary-process"

When visiting several of the entries at http://www.eljueves.es/feeds/rss.html in different tabs, WebKitGtk+ receives a SIGABRT.

This bug is not reproducible in a predictable way.

BT from gdb

I also have a 1.2G core, if needed.

I also have a BT from epiphany and a ~600M SIGSEV core from epiphany but I suppose that is caused by the SIGABRT in the WebKitGtk+ SIGBART in the UI process.

#6  0x00007fc69eef04e2 in std::__throw_bad_function_call() () from /usr/lib/x86_64-linux-gnu/libstdc++.so.6
#7  0x00007fc6a7e46b53 in std::function<void (WebCore::PolicyAction)>::operator()(WebCore::PolicyAction) const () from /opt/gnome-os/tanty/epiphany/install/lib/libwebkit2gtk-4.0.so.37

Looks like the std::function was null.

Also, "Thread 637" looks really bad. We shouldn't make more than 20-25 threads.

That is probably a separate bug worth reporting: the UI process should not crash during a web process crash (what you reported here is a web process crash).

Oh, right. Didn't realize the crashing process was <path_to>/libexec/webkit2gtk-4.0/WebKitWebProcess .

Check bug 147111.

Another similar BT from gdb

This happen when using WebKitGtk+ with my own JHBuild setting:
https://github.com/tanty/jhbuild-epiphany/tree/wkgtk-devel

Epiphany 3.18.0 and WebKit 2.10.0

I'm running Epiphany with the dconf key:

"process-model" = "shared-secondary-process"

The compilation was done with CMake args:

"-DPORT=GTK -DCMAKE_BUILD_TYPE=Debug -DDEVELOPER_MODE=ON -DCMAKE_C_FLAGS_DEBUG=-g1 -DCMAKE_CXX_FLAGS_DEBUG=-g1"

WebKitWebProcess crashed as described on bug 150670. Epiphany didn't crash and re-spawned another WebProcess. This second WebProcess crashed again in this way.

This bug is not reproducible in a predictable way.

Yet another similar BT from gdb

This one was obtained just running MiniBrowser.

[Andres Gomez Garcia]

Happens also in 2.10.3
