Workaround
----------
To work around the problem, do one of the following:
1. Change the register value to a nonregister value.
2. Put the quantity (x[p] + y[a]) into a temporary variable, then use
the temporary.
3. Compile with one or more of -Ol, -Oe, or -Og.
4. Use the C version 6.00a update, which corrects this problem.
A code example, which demonstrates this problem, is shown below:
Code Example
------------
#include <stdio.h>
unsigned y[200];
unsigned x[320];
char buffer[0x4000];
char far *scrn;
void test(p)
int p;
{
register a;
buffer[ x[p] + y[a] ] = scrn[ x[p] + y[a] ];
}
void main(void)
{
int b;
test(b);
}
