sublimegdb can not stop in the breakpoint

问题:

I hava install sublimeGDB in my sublime text 2, and my setting is right. Then I press F9 in a line to set a breakpoint. When I press F5 to run, I found my program can not stop on the breakpoint, and the program finished running. The information show below is "GDB session ended". The GDB view is appear in just 0.5 sec., and then disappear.
