Created attachment 285006 [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 2.13.4 with a couple of applied patches. I'm running Epiphany with the dconf key: "process-model" = "shared-secondary-process" The compilation was done with CMake args: '-DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_FLAGS_RELEASE="-O0 -g1 -DNDEBUG -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g1 -DNDEBUG -DG_DISABLE_CAST_CHECKS"' After visiting several pages, eventually, WebKitWebProcess hits a SIGTRAP. This bug is not reproducible in a predictable way.

That's rendering MathML, apparently.
