Oh, I see now what you mean. The bug is in _Uia64_get_kernel_table():
it should call get_kernel_table() only if kernel_table.u.ti.table_data
is still NULL (like it does in the call to tdep_find_proc_info).

No need to apologize.  I'm really glad someone is starting to push the
dynamic unwind info support in new ways, so this should be a useful
experience no matter what.
