Backport #7896: Can't test rb_iter_break with extensions

• Status: Closed
• Assignee: -

[naruse (Yui NARUSE)]

If you test rb_iter_break() with some extension library like trunk's ext/-test-/iter/break.c, it will cause SEGV on 1.9.3.
It won't happen on 2.0 because r34369 is accidentally fix it with below patch.

I noticed this because RubySpec added a test for rb_spec_iter (4db31b04954118e66ac1d6353ebf4106cb2b419b) and hit this.
