[ruby-ffi] Is the release interface supposed to swallow errors?

Hi,

ffi 1.9.0

I noticed that if I declare a struct using .auto_ptr, that the corresponding release method seems to swallow errors.

require 'ffi'

class Solaris
extend FFI::Library
ffi_lib :kstat

class KstatCtl < FFI::Struct
    layout(:kc_chain_id, :int, :kc_chain, :pointer, :kc_kd, :int)

    def self.release(pointer)
      puts "Releasing..." # Yep, I see this
      bogus # Shouldn't this raise an error? Instead, nothing happens.
    end
end

attach_function :kstat_open, [], KstatCtl.auto_ptr
attach_function :kstat_close, [KstatCtl], :int

def self.kstat
    kptr = kstat_open()
    kstat_close(kptr)
end
end

Solaris.kstat

What I'm really trying to do is have the release method call kstat_close inside the KstatCtl's release method. It fails, but I can't tell -why- it fails since the error is getting swallowed.

Help or advice appreciated.

Regards,

Dan
