this looks a false positive.

A portion of memory pointed to by ptr is indexed with i * 23 + m,
where i ranges from 0 to 3, inclusive, and m ranges from 0 to 22,
inclusive if i < 3, otherwise m ranges from 0 to 20, inclusive.
So the largest index value we compute equals 89 (3 * 23 + 20).
Because ptr points to something that is at least 90 bytes large,
89 is a valid index and no greater index will be ever computed.
