Can I call Array.new in Thread block?

[bggd]

This code is not work(segfault).

th = Thread.new do
  Array.new
end

a = th.join

I don't get segfalut.

I got join.rb:8: cannot migrate object (TypeError)

vs2012 with pthreads-for-win32 => TypeError.

mingw-w64 => segfault.

Hmm, It seens something bug. Hash.new works.

And it seems works with foo = []

quick-fix for this issue:
comment out initializer in mrblib/array.rb.and add to this code in src/array.c

MRB_API mrb_value
mrb_ary_initialize(mrb_state *mrb, mrb_value self)
{
  return mrb_ary_clear(mrb, self);
}

  mrb_define_method(mrb, a, "initialize", mrb_ary_initialize,    MRB_ARGS_NONE());

It seems mruby's bug.

Ah, I'm guessing cause is difference of symbol-id in another thread.

This should be fixed in e139cfe
