Created attachment 298341 [details] 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, bug 164052 and bug 165848, 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 -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.

Created attachment 300324 [details] BT from gdb for the WebProcess, 2.15.4 Still reproducible with Epiphany 3.22.5 and WebKit 2.15.4. I'm running Epiphany with the dconf key: "process-model" = "shared-secondary-process" And the env variable: "export G_DEBUG=fatal-criticals" The compilation was done with CMake args: '-DENABLE_THREADED_COMPOSITOR=OFF -DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DENABLE_MINIBROWSER=ON -DCMAKE_C_FLAGS_RELEASE="-O0 -g1 -DNDEBUG -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g1 -DNDEBUG -DG_DISABLE_CAST_CHECKS"'

Created attachment 300393 [details] BT from gdb for epiphany's WebApp Not exactly the same problem, but in case they are co-related and this can help to solve the problem(s). Running an Ephy WebApp with WKGTK+ 2.15.4, with: G_DEBUG=fatal-criticals and with the arguments: --application-mode --profile="/home/tanty/.config/epiphany/app-epiphany-facebook-82da67b211249624f24f3c7db5642a5112c9446f" https://www.facebook.com/
