Device with 2 cores having Global breakpoint enabled,

CPU1 running and CPU2 is halted on a Breakpoint.

Now running CPU2 makes CPU1 to Halt! With CPU2 continuing to be in running state.  

Run CPU1 and subsequently if CPU2 is halted manually or via a BP, CPU1 will sync halt since GBP are enabled for these 2 cores.

The GBP Halt works, but the observed behavior at is because of the following

1. When CPU2 is told to run from a BP, the debugger is issuing a step and a run to handle the breakpoint
2.  The initial step is effectively a halt after the step for the cross triggering
3. This halt before CPU2 goes into a full Running, causes CPU1 to halt due to GBP enabled 

Observed on F29.

This behavior is dependent on Architecture and/or BP type
