We're certainly interested. Linus started this a while ago but didn't get
to the point where he could make sense of the data... so there are some
old files but nothing that works.
We might even be able to get access to a Cochran dive computer to test

More than happy to help with that... where exactly does it happen? Can you
reliably reproduce it? Do you have a stack trace?

A good friend of mine who is a Trimix instructor has a Cochran. I'm sure I
could get access to that in order to test - it's a bit of driving to get
there, so I'd love to make sure we have pretty solid code before I do that
- ideally the ability to do a full dump (assuming that's supported by

I'd be interested in either. I'm traveling the next two weeks so it will
be a little while before I can get access to a Cochran, but in the
meantime we can track down your crash and address any other questions you
