Today ,I can’t debug my app,but I can run it. I have tried restart tizen studio and mechine but all the same error.   The error is follow:

Cannot launch application with GDBClient.
Error in final launch sequence
Failed to execute MI command:
-exec-continue
Error message from debugger back end:
Warning:\nCannot insert breakpoint 1.\nCannot access memory at address 0xb7934259\n
Warning:\nCannot insert breakpoint 1.\nCannot access memory at address 0xb7934259\n

What’t the problem and how to solve it ? Thanks a lot.
