[lldb-dev] negative in stop reason

[Jim Ingham via lldb-dev]

Negative breakpoint ID’s are used for breakpoints lldb sets for internal purposes. You can see the internal breakpoints with the “break list -i” command.

“continue” doesn’t usually need to set internal breakpoints, however.  And we don’t usually tell you about internal breakpoint hits, especially if you hit a user breakpoint at the same time.  So that is a little curious.  But I also wonder if you are hitting this breakpoint over and over?  What is the hit count on breakpoint 3?  You can see this in the output of “break list 3.1"
