QB64 Bug: LEN(integer variable) does not work

Program that produces the bug:
i% = 32767
PRINT LEN(i%)

QBASIC produces 2. QB64 produces C++ error.

LEN(non string variable) should return the size in bytes of the variable.

LEN(stringexpression$)
  or
LEN(variable)

    ■ stringexpression$ A string constant or string expression.
■ variable Identifies the object for which you want the
number of required bytes.

Returns
The number of characters in stringexpression$ or the number of bytes
required by variable.
