Global variable

[xiang san]

Hi

I have a strange question to ask for your help.In my program, I define and use a large number of global variables. However, when I define a global variable again and use it, the program will make an error. The phenomenon is that it keeps restarting. If it is defined as a local variable, the program also runs well. I think it is possible that it is caused by global variable overflow?

Thanks.
