Synopsis: Incorrect code when aliasing double and struct on ARM -O2

State-Changed-From-To: open->closed
State-Changed-By: toon
State-Changed-When: Mon Feb  4 13:29:02 2002
State-Changed-Why:
    User error.  The compiler is allowed to assume that the
    struct and the double aren't aliased.
    
    Use -fno-strict-aliasing if you want to compile this code
    with gcc.
