BT from gdb
I'm using WebKitGtk+ with my own JHBuild setting:
https://github.com/tanty/jhbuild-epiphany/tree/master
Epiphany 3.20.3 and WebKit 2.15.2 with the attached patches for bug 164049, bug 165200, bug 165283 and bug 164052, applied.
I'm running Epiphany with the dconf key:
"process-model" = "shared-secondary-process"
And the env variable:
"export LIBGL_DRI3_DISABLE=1"
The compilation was done with CMake args:
'-DENABLE_THREADED_COMPOSITOR=OFF -DUSE_LD_GOLD=OFF -DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DENABLE_MINIBROWSER=ON -DCMAKE_C_FLAGS_RELEASE="-O0 -g1 -DNDEBUG -DG_DEBUG=fatal-criticals -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g1 -DNDEBUG -DG_DEBUG=fatal-criticals -DG_DISABLE_CAST_CHECKS"'
After visiting several pages, eventually, the WebProcess hits a SIGSEV.
This bug is not reproducible in a predictable way.
The bug just happened after restoring a fullscreen youtube video to its original size inside a window.
