Description

Adding the following test to thread_test.rb shows the problem:

def test_thread_variables_work_for_dynamically_created_symbols
  t = Thread.new {}.join
  key_str = "foo#{rand}"
  key_sym = key_str.to_sym
  t.thread_variable_set(key_sym, "bar")
  assert_equal "bar", t.thread_variable_get(key_str)
  assert_equal "bar", t.thread_variable_get(key_sym)
end

Test output:

[15045/15894] TestThread#test_thread_variables_work_for_dynamically_created_symbols = 0.00        
  1) Failure:
TestThread#test_thread_variables_work_for_dynamically_created_symbols [/Users/stefan.kaes/src/ruby/test/ruby/test_thread.rb:94]:
<"bar"> expected but was
<nil>.
