optimization/8537: Optimizer Removes Code Necessary for Security

[fw@gcc.gnu.org]

Synopsis: Optimizer Removes Code Necessary for Security

State-Changed-From-To: open->closed
State-Changed-By: fw
State-Changed-When: Sun Nov 17 06:28:05 2002
State-Changed-Why:
    This is not a bug in GCC.  The call to memset() clear hasn't any externally visible effect according to the C language specification, so it can be removed by the optimizer.
    
    See the discussion around http://gcc.gnu.org/ml/gcc/2002-01/msg00518.html for additional information on a very similar topic.
