I don’t know why I am receiving this error?
What does this mean?
How can I delete it?
How can they hurt my show?
This is a widely used code snippet, I can hardly imagine it has such obvious errors, so I think valgrind will give you false positives. You can safely Ignore them.
Look I have a program
#include
int call(){
int x=25;
++x;
return x;
}
int main( ){
int ptr;
ptr=call();
printf("%d",ptr);
return 0;
}

These are not from your code, but from /lib/ld-*.so, which is a dynamic library loader.
This is a widely used code snippet, I can hardly imagine it has such obvious errors, so I think valgrind will give you false positives. You can safely ignore them.
