valgrind Error: Conditional jump or move depends on uninitialised value(s)

I have one program:

#include <stdio.h>

int  call(){ 
  int x=25; 
  ++x; 
  return x; 
} 

int main(){ 
  int p; 
  p=call(); 
  printf("%d",p);
  return 0;
} 

When I compile the program with -g option and run it with valgrind it shows:

==15469== ERROR SUMMARY: 13 errors from 8 contexts (suppressed: 0 from 0)

I don't know why I am getting this error.

What does it mean?

How can they harm my program?

How can I remove them?

---

These are not from your code, but from /lib/ld-*.so which is the dynamic library loader.

This is such a widely used piece of code that I can hardly imagine that it has such an obvious bug, so I think valgrind is giving you false positives. You can probably safely ignore them.

---

Though this is coming from system libraries and has nothing to do with your code (and looks harmless) ensure that you have correct .supp files in /usr/lib/valgrind directory. Corresponding to your glibc version, there would be a section which suppresses such error messages:

#-------- glibc 2.3.4/ Fedora Core 3
{
   dl_relocate_object
   Memcheck:Cond
   fun:_dl_relocate_object
}

Maybe you want to check your valgrind's installation.
