Created attachment 282896 [details] BT from gdb I'm using WebKitGtk+ with my own JHBuild setting: https://github.com/tanty/jhbuild-epiphany/tree/master Cairo 1.14.2, Epiphany 3.20.1 and WebKit 2.12.3 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"' When visiting several pages, eventually, WebKitWebProcess hits a SIGABRT. This bug is not reproducible in a predictable way.

I know the SIGABRT happens in Cairo but the comment at: https://bugs.freedesktop.org/show_bug.cgi?id=78787#c6 Suggests that it is not a bug, but an error from the code using cairo (I cannot see how an assert in private API can be so, but I haven't digged).
