Reading specs from /usr/lib/gcc-lib/i586-mandrake-linux/2.96/specs
gcc version 2.96 20000731 (Linux-Mandrake 7.2)
>Description:
The printout order is different between optimized and unoptimized code.
The optimized code seems correct.
(My code is "wrong")

[root@back 21dayscpp]# g++ -Wall hello.cxx -ohello2
[root@back 21dayscpp]# ./hello2 
Hello World!

12 : 35Test
Enter value 1
6
Enter value 2
7
second: 6
first: 6


[root@back 21dayscpp]# g++ -Wall -O hello.cxx -ohello2
[root@back 21dayscpp]# ./hello2 
Hello World!

12 : 35Test
Enter value 1
6
Enter value 2
7
first: second: 6
6
>How-To-Repeat:
This produces incorrect code:
g++ -Wall hello.cxx -ohello 

This produces correct code:
g++ -Wall -O hello.cxx -ohello
