It is possible that NATIVE_HBOOL is internally stored in a way (e.: int) that
results in size > 100 for your array (for int, size==400 on a 32-bit
machine). Your sizeof() call may not provide the correct amount of memory for
your actual array - only for the instance of the ArrayType class
that "represents" the storage you want.
