There is a potential bug in Win32lib similar to the allocate_string bug:

Currently:

global function allocate_struct( integer size)
        -- allocate space for a structure
        -- and initialize to zero

        atom at

        at  = allocate( size )
        mem_set( at, 0, size )
        return at
end function


Should(?) change to:

global function allocate_struct( integer size)

        -- allocate space for a structure
        -- and initialize to zero

        atom at

        at  = allocate( size )
        if at != 0 then
            mem_set( at, 0, size )
            return at
        end if
        return 0

end function
