Created attachment 359364 [details] GDB backtrace While trying to debug this crash on BOINC Manager gui https://github.com/BOINC/boinc/issues/2350 by looking at GDB backtrace (see attachment) and Valgrind output (hereunder), I think it is a problem Webkit, in particular you get a SIGSEGV: segmentation violation at the function webkitWebViewBaseCreateWebPage(_WebKitWebViewBase*, WTF::Ref<API::PageConfiguration, WTF::DumbPtrTraits<API::PageConfiguration> >&&) of file WebKitWebViewBase.cpp:1364 Libraries version I am using: webkit2gtk3-2.22.5-1.fc29.x86_64 wxBase3-3.0.4-4.fc29.x86_64 wxGTK3-3.0.4-4.fc29.x86_64 wxGTK3-webview-3.0.4-4.fc29.x86_64 Valgrind output when BOINC Manager crashes: ==6052== ==6052== HEAP SUMMARY: ==6052== in use at exit: 10,297,642 bytes in 84,663 blocks ==6052== total heap usage: 1,338,545 allocs, 1,253,882 frees, 1,767,724,014 bytes allocated ==6052== ==6052== LEAK SUMMARY: ==6052== definitely lost: 364,320 bytes in 1,312 blocks ==6052== indirectly lost: 418,708 bytes in 13,602 blocks ==6052== possibly lost: 8,109 bytes in 113 blocks ==6052== still reachable: 8,861,441 bytes in 64,897 blocks ==6052== of which reachable via heuristic: ==6052== length64 : 9,888 bytes in 147 blocks ==6052== newarray : 49,560 bytes in 78 blocks ==6052== suppressed: 0 bytes in 0 blocks ==6052== Rerun with --leak-check=full to see details of leaked memory ==6052== ==6052== For counts of detected and suppressed errors, rerun with: -v ==6052== Use --track-origins=yes to see where uninitialised values come from ==6052== ERROR SUMMARY: 189 errors from 6 contexts (suppressed: 0 from 0) ==5953== Invalid read of size 8 ==5953== at 0x6874D7A: g_dbus_server_get_client_address (gdbusserver.c:518) ==5953== by 0x4996134: wxgtk_initialize_web_extensions (webview_webkit2.cpp:367) ==5953== by 0x69553DC: g_closure_invoke (gclosure.c:810) ==5953== by 0x6968982: signal_emit_unlocked_R (gsignal.c:3635) ==5953== by 0x6971AA9: g_signal_emit_valist (gsignal.c:3391) ==5953== by 0x69720A2: g_signal_emit (gsignal.c:3447) ==5953== by 0x77EA6A6: webkitWebContextInitializeWebExtensions(_WebKitWebContext*) (WebKitWebContext.cpp:1600) ==5953== by 0x77D1499: WebKitInjectedBundleClient::getInjectedBundleInitializationUserData(WebKit::WebProcessPool&) (WebKitInjectedBundleClient.cpp:136) ==5953== by 0x7754E2C: WebKit::WebProcessPool::initializeNewWebProcess(WebKit::WebProcessProxy&, WebKit::WebsiteDataStore&) (WebProcessPool.cpp:982) ==5953== by 0x775500D: WebKit::WebProcessPool::createNewWebProcess(WebKit::WebsiteDataStore&, WebKit::WebProcessProxy::IsInPrewarmedPool) (WebProcessPool.cpp:797) ==5953== by 0x77554D3: WebKit::WebProcessPool::createWebPage(WebKit::PageClient&, WTF::Ref<API::PageConfiguration, WTF::DumbPtrTraits<API::PageConfiguration> >&&) (WebProcessPool.cpp:1180) ==5953== by 0x780E9DD: webkitWebViewBaseCreateWebPage(_WebKitWebViewBase*, WTF::Ref<API::PageConfiguration, WTF::DumbPtrTraits<API::PageConfiguration> >&&) (WebKitWebViewBase.cpp:1364) ==5953== Address 0x11000000110 is not stack'd, malloc'd or (recently) free'd ==5953== ==5953== ==5953== HEAP SUMMARY: ==5953== in use at exit: 10,301,652 bytes in 84,670 blocks ==5953== total heap usage: 1,338,587 allocs, 1,253,917 frees, 1,767,726,032 bytes allocated ==5953== ==5953== LEAK SUMMARY: ==5953== definitely lost: 351,824 bytes in 1,295 blocks ==5953== indirectly lost: 418,612 bytes in 13,598 blocks ==5953== possibly lost: 12,141 bytes in 122 blocks ==5953== still reachable: 8,874,011 bytes in 64,916 blocks ==5953== of which reachable via heuristic: ==5953== length64 : 9,888 bytes in 147 blocks ==5953== newarray : 49,560 bytes in 78 blocks ==5953== suppressed: 0 bytes in 0 blocks ==5953== Rerun with --leak-check=full to see details of leaked memory ==5953== ==5953== For counts of detected and suppressed errors, rerun with: -v ==5953== Use --track-origins=yes to see where uninitialised values come from ==5953== ERROR SUMMARY: 193 errors from 7 contexts (suppressed: 0 from 0)
