It is possible for multiple breakpoints to specify the same event, or possibly overlapping events. Thus, more that one breakpoint detector may trigger at the same time.
When more than one breakpoint detector triggers, the thread filters and logical filters of all the breakpoints involved are processed before the action part of any breakpoint is performed.
After the set of breakpoints that trigger is determined, the action parts of each of them are performed in an undefined order.
After all action parts are performed, execution of the program is resumed only if all of the breakpoints so specify in their disposition. If any one of them specifies a break, the debugger prompts you for further commands.
