47

Addition or subtraction of a pointer into, or just beyond, an array object and an integer type produces a result that points just beyond the array object and is used as the operand of a unary * operator that is evaluated.

ARR30-C. Do not form or use out of bounds pointers or array subscripts Dereferencing Past the End Pointer, ARR30-C. Do not form or use out of bounds pointers or array subscripts

49

An array subscript is out of range, even if an object is apparently accessible with the given subscript (as in the lvalue expression a[1][7] given the declaration int a[4][5]).

ARR30-C. Do not form or use out of bounds pointers or array subscripts

62

An attempt is made to access, or generate a pointer to just past, a flexible array member of a structure when the referenced object provides no elements for that array.

ARR30-C. Do not form or use out of bounds pointers or array subscripts
