BT from gdb for the WebProcess
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:
'-DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DENABLE_MINIBROWSER=ON -DCMAKE_C_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DISABLE_CAST_CHECKS"'
After visiting several pages, eventually, the WebProcess hits a Critical.
This bug is not reproducible in a predictable way.</pre>
