Several of these fields appear to be garbage.  next is garbage, you
found.  nargs is garbage.  function is garbage.

The next step is to manually scan the same list, starting with
backtrace_list, and see what elements it has before that point.
And see what they say.  What functions made them?

This will give us a clue towards how the list got clobbered as it did.
