Created attachment 303050 [details] BT from gdb for the WebProcess Created attachment 303048 [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 3.22.6 and WebKit 2.15.90. However, the rest of the dependencies, but mesa and its dependencies, and evince, are all provided from Debian Testing. 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 SIGSEV. This bug is not reproducible in a predictable way.

This SIGSEV is not difficult to hit, although not in a predictable way.
