- Author: Nobuyoshi N.

Fiddle::Function#call seems leaking memory.
With the following code:
# fiddle-memleak.rb
require 'fiddle'
n = 10
a = ["a"] * n
f = Fiddle::Function.new(Fiddle.dlopen(nil)["rb_obj_tainted"],
[Fiddle::TYPE_VOIDP]*n, Fiddle::TYPE_VOID)
loop {f.call(*a); GC.start}
VSZ and RSS increase continuaslly.
$ ruby fiddle-memleak.rb & while ps -ovsz=,rss= $!; do sleep 1; done

RGenGC seems unrelated since the result in 2.0.0 is similar.
