Not necessarily right, the process of issuing a signal to the core may Oh, Oh What I mean is that with O option, Debugging with gdb, core position of the corresponding code will be different, such as 100 firms originally, but now 90 do? O, and g is the conflict? Gcc-g-O, the mode itself may have problems. For example, a variable was the actual optimization off, but l orders will be listed as related code, but you could not stop there.
