MobileNet example is not working with Sipeed_GC0328

[TA-Robot]

I tried to use working mobilenet example with Sipeed_GC0328. But it's not working.
When mbnet.show() function called, it clashed with core dump like below.

Please fix this or give me example with Sipeed_GC0328!

I don't know I totally solved this problem, but now my program working!

In my case, above core dump gone after adding "return 0;" to last of int MBNet_1000::show() function.

this make so good.

getting similar issue, could not identify the source of the problem.
MBNet_1000:show() function have return type void in example program so return 0 is not required.
