[ngoto (Naohisa Goto)]

On Solaris 10, sparc architecture, when compiling ruby (r63417) by GCC (version 4.6.2), TestThread#test_join_limits did not end.

The test ended successfully when compiling ruby by Oracle Developer Studio 12.5 or 12.6.

Split TestThread#test_join_limits into peaces

• test/ruby/test_thread.rb (TestThread#test_join_limit_*): Split
  TestThread#test_join_limits for investigating hang-up on Solaris.
  Each method tests only a single limit value.

After splitting the test, TestThread#test_join_limit_negative_INT64_MIN fails.
i.e. limit=RbConfig::LIMITS['INT64_MIN']; t = Thread.new { sleep }; t.join(limit) hangs up.

[ngoto (Naohisa Goto)]

In the above situation when the test fails, RbConfig::LIMITS['INT64_MIN'] is nil.

[nobu (Nobuyoshi Nakada)]

Does RbConfig::LIMITS have 'INT64_MIN' key?
Or the default nil?
