optimization/6475: zlib miscompilation with gcc-3.1

[jakub@gcc.gnu.org]

Synopsis: zlib miscompilation with gcc-3.1

State-Changed-From-To: open->analyzed
State-Changed-By: jakub
State-Changed-When: Fri Apr 26 05:54:19 2002
State-Changed-Why:
    Fails with -O2 -mcpu=i686 -fPIC as well (though a different
    test) before 20020420 or if http://gcc.gnu.org/ml/gcc-patches/2002-04/msg01041.html
    is backed out from current source; that patch looks just
    if it is hiding the symptoms of a bug.
