Compiling the sample code below with Microsoft C versions 6.00 and
6.00a using any combination of optimizations that have /Oe included
will result in the following internal compiler error:

Internal Compiler Error in C 6.00
---------------------------------

   foo.c(17) : fatal error C1001: Internal Compiler Error
           (compiler file '@(#)exphelp.c:1.115', line 370)
           Contact Microsoft Product Support Services

Internal Compiler Error in C 6.00a
----------------------------------

   foo.c(17) : fatal error C1001: Internal Compiler Error
           (compiler file '@(#)regMD.c:1.110', line 725)
           Contact Microsoft Product Support Services

Disabling the /Oe optimization will correct this error.

Sample Code
-----------

void foo(int boo, int hoo)
{
        int x;
        int y;
        int Foo[4];
        int Bar[4];
        int i;

        for (i=0; i<4; i++) Foo[i] = Bar[i] = i;
        if (boo)
        {
                y = Foo[hoo];
                x = Bar[boo];
                Foo[x] = y;
                Foo[hoo] = boo;
                Bar[boo] = hoo;
        }
}

Microsoft has confirmed this to be a problem in Microsoft C versions
6.00 and 6.00a. We are researching this problem and will post new
information here as it becomes available.
