BT from gdb for the WebProcess

I'm using WebKitGtk+ with my own JHBuild setting:

Epiphany 3.20.3 and WebKit 2.15.2 with the attached patches for bug 164049, bug 165200, bug 165283 and bug 164052, applied, and also the modification suggested at https://bugs.webkit.org/show_bug.cgi?id=165848#c18

I'm running Epiphany with the dconf key:

"process-model" = "shared-secondary-process"

And the env variable:


The compilation was done with CMake args:


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.)
