First of all, normally sprintf is used for writing something into a string.

Second, maybe you need to set these checkboxes in the project settings:

Thanks,I have this done in my code still I am facing the same issue.​

Also note that printf/sprintf (and maybe sscanf, not sure) use the heap and a failed allocation can cause a crash.

Just add 

#include<cstdio>

I'm not sure but I think you may send or receive some data is not char or not ascii. 
Or you may send or read data oversize from your buffer so you had write in some address which it's may affect to another function and then that function is fail.

Would it be possible to share the part of the code you changed yourselves?

This way we will be more able to assist.
