In general:

[alex@lancelot blm]$ strace -e stat64 python2.2 -S -c pass 2>&1 | wc -l
     18
[alex@lancelot blm]$ strace -e stat64 python2.3 -S -c pass 2>&1 | wc -l
     71
[alex@lancelot blm]$ strace -e fstat64 python2.2 -S -c pass 2>&1 | wc -l
      8
[alex@lancelot blm]$ strace -e fstat64 python2.3 -S -c pass 2>&1 | wc -l
     71
[alex@lancelot blm]$

Of the stat64 calls, the found-files only:

[alex@lancelot blm]$ strace -e stat64 python2.2 -S -c pass 2>&1 | grep -v 
ENOENT | wc -l
      4
[alex@lancelot blm]$ strace -e stat64 python2.3 -S -c pass 2>&1 | grep -v 
ENOENT | wc -l
     12
