	* thread_pthread.c: get current main thread stack size, which may
	  be expanded than allocated size at initialization, by rlimit().
	  [ruby-core:60113] [Bug #9454]

	* thread_pthread.c: rlimit is only available on Linux.
	  At least r44712 breaks FreeBSD.
	  [ruby-core:60113] [Bug #9454]

	* thread_pthread.c (ruby_init_stack, ruby_stack_overflowed_p):
	  place get_stack above others to get stack boundary information.
	  [ruby-core:60113] [Bug #9454]

	eval.c: remove unneeded GC guard

	* eval.c (setup_exception): remove RB_GC_GUARD which is no longer
  needed since r41598.
	* eval.c (setup_exception): preserve errinfo across calling #to_s
	  method on the exception.  [ruby-core:61091] [Bug #9568]

test_exception.rb: ignore SystemStackError

2013-12-10T14:02:16+00:00

* test/ruby/test_exception.rb (test_machine_stackoverflow): ignore
  propagated SystemStackError, which has not bee rescued in the
  child process by unknown reason.

test_exception.rb: enclose hash defininition

2013-11-20T09:01:42+00:00

* test/ruby/test_exception.rb: (test_machine_stackoverflow): enclose
  hash defininition because SystemStackError raises at line 3 on
  FreeBSD, for unknown reason.

eval_intern.h: refine stack overflow detection

2013-11-18T13:47:56+00:00

* eval_intern.h (TH_PUSH_TAG, TH_EXEC_TAG): refine stack overflow
  detection.  chain local tag after setjmp() successed on it, because
  calling setjmp() also can overflow the stack.
  [ruby-dev:47804] [Bug #9109]
* vm_eval.c (rb_catch_obj): now th->tag points previous tag until
  TH_EXEC_TAG().

2013-11-10T13:16:33+00:00

* vm_insnhelper.c (vm_push_frame): fix stack overflow check codes.

2013-08-06T08:33:05+00:00

  Stack overflow check should be done *after* pushing a stack frame.
  However, some stack overflow checking codes checked *before*
  pushing a stack frame with iseq->stack_max.
  To solve this problem, add a new parameter `stack_max' to specify
  a possible consuming stack size.
* vm_core.h (CHECK_VM_STACK_OVERFLOW0): add to share the stack overflow
  checking code.
* insns.def: catch up this change.
* vm.c, vm_eval.c: ditto.
* test/ruby/test_exception.rb: add a stack overflow test.
  This code is reported by nobu.
