rb_obj_equal() is specially optimized in
opt_eq_func()@vm_insnhelper.c.

All symbols have an fstring entry, and we initialize symbol tables
with 1000 bins. This reduces resizes during startup.

key first.
Garbage keys can be swept by lazy sweeping invoked by creating new
fstring. So that simply do:
(1) delete garbage key and return `fstr_update_callback' immediately
(2) try again `fstr_update_callback()' to create a new fstr.
This bug can be cause memory corruption, reported by

RBASIC_SET_CLASS() because it insert write barriers to fake
(non-RVALUE) structure.
It can cause unexpected behaviour.
Ruby 2.1 also have a same problem (setup_fake_str() in parse.y).
* symbol.c (setup_fake_str): ditto.
