This config should just run through a 'make oldconfig' fine and if the bzImage is built, it should produce the slab corruption messages on any typical 64-bit PC. I've attached the boot log below as well. (You can see the gcc version i used in the bootup log as well.) I'll disable MAXSMP in these testruns - just to establish the stability without any of the dynamic-cpumask_t stuff.
