[lldb-dev] break on exceptions/windows

[Greg Clayton via lldb-dev]

You should talk to Jim Ingham on this. We have special exception breakpoints that we did for Swift and you will want to follow the same methodology. I am not sure what the methodology is so I'm CC'ing Jim so can can comment.

If you're working in a fork and you don't intend to upstream any changes, you could just modify the default case of the switch statement there to not return ExceptionResult::SendToApplication.

For this you'd need to implement a new command so that you could do something like "break set --exception 0xC0000005" and pass that information to the ProcessWindowsLive plugin somehow, so that it could decide when to break and when to pass it on to the application for a second chance.
