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.

This SIGSEV seems to happen very easily.

Can you try applying r221008 on top of your build?

Comment 4 Michael Catanzaro 2017-08-28 04:24:12 PDT 
Should that commit be added to https://trac.webkit.org/wiki/WebKitGTK/2.18.x?
