Message <Context> pointer arithmetic was performed more than once in computing an array element. The bounds checking code output by the compiler will only verify the "<expr>" expression. Description When an array is accessed using pointer arithmetic and run-time array bounds checking is enabled, the HP C compiler is only able to output the checking code for the first pointer arithmetic operation performed on the array. This can result in an incorrect check if the resulting pointer value is again operated on by pointer arithmetic. Consider the expression a = b + c - d; where a is a pointer, b an array, and c and d integers. When bounds checking is enabled the compiler will output a check to verify that c within the bounds of the array. This will lead to an incorrect runtime trap in cases where c is outside the bounds of the array and c - d is not. User Action Recode the pointer expression so that the integer part is in parenthesis. This way the expression will contain only one pointer arithmetic operation. In the earlier example the expression would be changed to a = b + (c - d);
