This is a bug about confusing between GCC 4.3 and GCC 4.4.

So, I fixed the problem using temporary solution.

Edit the stdio.h

#ifdef __USE_GNU
/* This function does the same as `fgets' but does not lock the stream.

   This function is not part of POSIX and therefore no official
   cancellation point.  But due to similarity with an POSIX interface
   or due to the implementation it is a cancellation point and
   therefore not marked with __THROW.  */
extern char *fgets_unlocked (char *__restrict __s, int __n,
                             FILE *__restrict __stream) __wur;
#endif

-->

extern char *fgets_unlocked (char *__restrict __s, int __n,
                             FILE *__restrict __stream) __wur;

extern _IO_ssize_t __getdelim (char **__restrict __lineptr,
                               size_t *__restrict __n, int __delimiter,
                               FILE *__restrict __stream) __wur;

#endif

It is a temporary fixed. so, We need to patch the CMSSW gcc version.
