Breakpoint disable will keep the breakpoint around and all of its locations. Breakpoint delete will delete it. Shouldn't make a difference and one doesn't have to happen before the other. Sounds like you found a bug. When things crash it would be good to attach a stack backtrace of why LLDB is crashing. That will help us to see what us causing the issue.
