DavidSpickett added a comment.
Turns out comparing thread.get_thread_frames() doesn't work because
you end up getting references to the same frames. Instead save the info
we want to compare.
One obvious reason this tactic should have failed is that the libc raise
frame will have a different ID between the two backtraces. This is why I've
ignored ID in the comparion.
Doing this showed me that sp and fp should be set, so I've got fp from
the sigcontext also.
