  -----------
  Silence potential overflow warning (#83272)

Cast Offset variable to int64_t type directly inside a multiplication
and function call to utilize 64-bit arithmetic.

Ensure that the multiplication will not overflow.

A static analyzer warned about this since the function expects a 64-bit
argument, but the multiplication is evaluated inside a 32-bit context.
