Summary: memory leakage in DL module

Initial Comment:

asume the folowing file a.c

int func (int a , int b) {
 return (a+b);
}

compiled with cc -o a.so --shared a.c this give you a.so


when execute the following ruby file with memprofile under linux
once the script has reached the gets function.
You can see an important  memory leak.

when doining a similar trial with "void func();" there is no leak

require 'dl/import'
module LIBC
extend DL::Importable
p dlload './a.so'
  p extern "int func (int,int)"
end

10000.times {
 p LIBC.func(3,2)
}
gets


additional info : 
    ruby 1.8.1 (2003-12-25) [i386-linux-gnu]
    memprof 0.5.1
    std fedora core 3 install.
