Description of problem:
On RHEL5, strace always returns 0 even though traced command exit with non-zero value.
On RHEL6, strace returnes same value as traced command's exit code.


Version-Release number of selected component (if applicable):
strace-4.5.18-18.el5 from RHEL5.9 beta.

How reproducible:
Always

Steps to Reproduce:
1.  strace ls alsdkjasldkja
2.  echo $?
  
Actual results:

echo $?
0

Expected results:
echo $?
2

Additional info:
This symptom was reported on Fedora (BZ#105371) and fixed on F10 era.
And the fix is in RHEL6 since RHEL6 is based on Fedora 14.

On RHEL6 example.

# strace ls adalskdjalsdkj

close(1)                                = 0
close(2)                                = 0
exit_group(2)                           = ?
# echo $?
2         <==


But the fix was not backported to RHEL5, so it still have the problem.

On man page of strace, it is documented.
> When  command exits, strace exits with the same exit status. 

But currently, strace on RHEL5 doesn't work as it is documented.
