    Subject[CRYPTO]: Miscompiling sha256.c by gcc 3.2.3 and arch pentium3,4
    2.6.2-rc2 sha256.c is miscompiled with gcc 3.2.3.
    (User space is RedHat 3ES.)

    Just an observation:

    gcc 3.2.3 is miscompiling sha256.c when using
    -O2 -march=pentium3
    or pentium4.

    gcc 3.3.x is ok, or the problem disappears
    if I use arch=i686 or reduce the optimisation level to -O2.

    Sympthoms are all the sha256 test vectors fail.
    If I extract the guts of the file to compile in user space
    the same problem occurs.
