BT from gdb for the WebProcess
I'm using WebKitGtk+ with my own JHBuild setting:
<a href="https://github.com/tanty/jhbuild-epiphany/tree/master">https://github.com/tanty/jhbuild-epiphany/tree/master</a>

I'm running Epiphany with the dconf key:
"process-model" = "shared-secondary-process"
And the env variable:
"export LIBGL_DRI3_DISABLE=1"
The compilation was done with CMake args:
'-DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DENABLE_MINIBROWSER=ON -DCMAKE_C_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DEBUG=fatal-criticals -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DEBUG=fatal-criticals -DG_DISABLE_CAST_CHECKS"'
After visiting several pages, eventually, the WebProcess hits a SIGTRAP.
This bug is not reproducible in a predictable way.
This the error message:
-- 8< -- 8< -- 8< -- 8< -- 8< -- 8< -- 8< --
(WebKitWebProcess:20587): Gdk-ERROR **: The program 'WebKitWebProcess' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAccess (attempt to access private resource denied)'.
(Details: serial 13421095 error_code 10 request_code 130 (MIT-SHM) minor_code 1)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
