merge revision(s) 43748,45947,45951: [Backport #9739]
* eval_intern.h (SAVE_ROOT_JMPBUF): workaround for the failure of
test/ruby/test_exception.rb on Windows.
wrap by __try and __exception statements on mswin to raise SIGSEGV
when EXCEPTION_STACK_OVERFLOW is occurred, because MSVCRT doesn't
handle the exception.
however, (1) mingw-gcc doesn't support __try and __exception
statements, and (2) we cannot retry SystemStackError after this
change yet (maybe crashed) because SEH and longjmp() are too
uncongenial.
* signal.c (check_stack_overflow, CHECK_STACK_OVERFLOW): now defined on
Windows, too.
* thread_win32.c (ruby_stack_overflowed_p): ditto.
* thread_win32.c (rb_w32_stack_overflow_handler): use Structured
Exception Handling by Addvectoredexceptionhandler() for machine
stack overflow on mingw.
This would be equivalent to the handling using __try and __exept
on mswin introduced by r43748.
Exception Handling by AddVectoredExceptionHandler() for machine
This would be equivalent to the handling using __try and __except
