Yes, thank you.  But did you see my feedback about some of the error
output, when I tested your branch?
Do you have a list of existing issues?
I can fairly easily test your experimental branch on a series of
vmcores, if that helps.

Here's the feedback, cut/pasted from the other email thread:

I'm seeing a lot of "invalid input" displayed like the below when
using the 'bt' command.  Is this a known issue?

bt: invalid input: "jne"
bt: invalid input: "mov"
bt: invalid input: "movl"
bt: invalid input: "jne"
bt: invalid input: "jne"
bt: invalid input: "jne"
bt: invalid input: "rep"
bt: invalid input: "je"
bt: invalid input: "je"
bt: invalid input: "je"
bt: invalid input: "call"
bt: invalid input: "call"
bt: invalid input: "jne"
bt: invalid input: "call"
bt: invalid input: "call"
bt: invalid input: "movl"
bt: invalid input: "mov"
bt: invalid input: "jne"
bt: invalid input: "mov"
bt: invalid input: "je"
bt: invalid input: "call"
