Description of problem:
The C++ compiler from package gcc-c++-2.96-112.7.1 incorrectly assigns addresses
for temporaries when compiling with -O and using inline functions.  The attached
program (a.cc) prints the address of each object as it is constructed and as it
is destroyed.  You can see that two of the temporaries are assigned to the same
location in memory and both are simultaneously alive (that is, both are
constructed, then both are destroyed).

This bug does not occur if the program is compiled without -O or if the function
"func" is not declared as inline.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Compile the attached program: g++ -O a.cc
2. Run the executable: ./a.out
3. Check the output, and see that two constructors are called for the same
address, then two destructors are called for that address.
	

Actual Results:  [stern@ida x]$ g++ -O a.cc
[stern@ida x]$ ./a.out
Cons-1 at 0xbffffaf0
Cons-1 at 0xbffffae0
Cons-2 at 0xbffffb00
Cons-1 at 0xbffffaf0
Cons-2 at 0xbffffb10
Dest at 0xbffffb00
Dest at 0xbffffaf0
Dest at 0xbffffaf0
Dest at 0xbffffae0
Dest at 0xbffffb10


Expected Results:  The second line of output saying "Cons-1 at 0xbffffaf0"
should refer to a different address, and similarly the second line saying "Dest
at 0xbffffaf0" should refer to that different address.

Alternatively, the address could be reused if the first destructor was called
before the second constructor.
