If the sample code below is compiled with the Microsoft C Compiler
version 6.00, using /AL and /Oe, the following internal compiler error
will be generated:

   C1001: Internal Compiler Error
   (compiler file '@(#)codegen.x:1.148', line 559)
   Contact Microsoft Product Support Services

This error will not be generated if the /Oe optimization is used with
/Og and/or /Ol. Microsoft has confirmed this to be a problem in
Microsoft C version 6.00. This problem has been corrected in Microsoft
C version 6.00a.

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

#define DB_PTERM_PTR(id)  (db_ptr[id] ? db_ptr[id] : db_swap_in(id))

extern DBRS_PTERM *db_swap_in(int);
extern DBRS_PTERM **db_ptr;

typedef struct
{
   int type;
   int factors[1];
}  DBRS_PTERM;

void foo(int pt_id)
{
   int id;
   int i, j, k;

   j = 0;
   for (i=0;(id=DB_PTERM_PTR(pt_id)->factors[i]) != 0; i++)
   {
      for(k=j;k>=0;--k)
      {}
      DB_PTERM_PTR(pt_id)->factors[j++] = id;
   }
}
