Created attachment 270203 [details] BT from gdb I'm using WebKitGtk+ with my own JHBuild setting: https://github.com/tanty/jhbuild-epiphany/tree/master Epiphany 3.18.0 and WebKit 2.10.6 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 SIGBUS and terminates. This doesn't kill epiphany, which is able to span another WebKitWebProcess and continue browsing after reloading the tab. This bug is not reproducible in a predictable way.

I'm reproducing this without much difficulty, but not in a predictable way.

Created attachment 283516 [details] Another similar BT from gdb Replacing the previous BT, which was mixing 2 different BT in the same file, from this and another bug. This BT only shows the output for this bug.

Created attachment 283517 [details] BT from gdb with 2.12.3 I think this is the first time I suffer something similar after wiping out my machine and installing a fresh Debian Testing. Still, the compilation is done with JHBuild with the same settings than used before.
