The code below, when compiled with Microsoft C 6.00, produces the
following error message:

   fatal error C1001: Internal Compiler Error
    (compiler file '../grammar.c', line 140)
    Contact Microsoft Product Support Services

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

struct x
{
   int a;
   int *b;
   double **c;
};

typedef struct x TEST;

void function (TEST *pTEST)
{
   double xx = 0;
   int i,j;

   for (i=0;i<pTEST->a;i++)

      for(j=0;j<pTEST->b[i];j++)

         if (pTEST->c[i][j]>xx)        // Fails here...

            pTEST->b[i]=j;
}

Compiling this code with one of the following options will produce
the internal compiler error mentioned above:

   /Ot /Oi /Oit

The following are some possible solutions:

1. Use /Oe, /Ol, /Ox, /Oet, or /Olt when compiling.

2. Put the typedef and struct x definitions together.

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