Yes! Missed those. Thanks.

I've not used gdb in the last 10-15 years (!). Any ideas how to stop the
code and see what it is doing when it is 100% locked? As I can't ctrl-c
the code when it is locked, I'm not sure how to stop it.

What I really need is a

set break when CPU=100%

command, but I doubt that exists....

Or do you not need any more help from me now that you can reproduce?
