I put the input and outputs at the attachment zif file. And the configure of 'flags' as follow, it says that the demo using the 'rtpghi' algorithm for phase propagation.

Thank you for providing details. There is definitely a noticeable difference in results. I can also reproduce your result obtained with phasecvocoder.m.
It is difficult to judge with the shifted (instead of stretched) output, but if I play the output from the executable at half speed and the twice stretched output of phasevocoder.m, my subjective impression is that the latter is closer in timbre to the input. The result from the executable has a roughness/mid-frequency noise that is not present, or at least much weaker, in the input. As a consequence, the shifted signal from the executable sounds 'richer', but I would argue that this is an artifact. I would actually prefer the phasevocoder.m output.
Nonetheless, we should figure out where the difference comes from. I will try digging out the source of the executable, but that will take some time.

Thank you for your replay, and I'm looking forward to it.
