If the compiler stops tracking 'vector', and the garbage collector frees
it, doesn't that cause XVECTOR (vector)->contents to be overwritten?  In
the debugging session in my second message in this thread I had a
hardware watchpoint on what vectorp was pointing at and it went off in
setup_on_free_list.

I'll see if I can figure that out.

Is there an easy way to print the function binding of a Lisp symbol from
gdb?
