Created attachment 319077 [details] BT from gdb for the WebProcess I'm using WebKitGtk+ with my own JHBuild setting: https://github.com/tanty/jhbuild-epiphany/tree/master Epiphany 3.24.1 and WebKit 2.17.91. The compilation was done with CMake args: '-DDEBUG_FISSION=OFF -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 SIGSEV. This bug is not reproducible in a predictable way.

Can you try applying r221008 on top of your build? https://trac.webkit.org/changeset/221008/webkit

Should that commit be added to https://trac.webkit.org/wiki/WebKitGTK/2.18.x?
