That's the value from mark_vectorlike?  It's moved a bit:

#9  0x00005555556d6d7e in mark_vectorlike (header=header <at> entry=0x7ffff19a4190)
    at alloc.c:6280

But it says:

(gdb) find &globals,&globals+1,0x7ffff19a4190
Pattern not found.

The machine is unfortunately deep inside my private network, so there's
no easy way to allow ssh to it...
