07:42 AM Ruby Bug #16814: Segmentation fault in GC while running test/ruby/test_fiber.rb on s390x

On s390x, `FIBER_POOL_ALLOCATION_FREE` is enabled. The doubly linked list of `fiber_pool->vacancies` assumes that the head `fiber_pool_vacancy` has `NULL` in its `previous` field. However, when a fiber is released, `fiber_pool_vacancy_... ReiOdaira (Rei Odaira)

11:05 PM Ruby Bug #16814: Segmentation fault in GC while running test/ruby/test_fiber.rb on s390x

Did you mean`any->as.data.dfree`? It points to no valid location.

11:54 PM Ruby Misc #16360: Enabling IBM PowerPC/Z cases in Travis CI

I'm happy to work for ppc64le and s390x. In the last few years, the number of the platform-specific issues that showed up in ppc64le and s390x Ruby has been between 5 and 10 every year, so I assume the same pace for my obligation as a m... ReiOdaira (Rei Odaira)

04:57 PM Ruby Feature #13637: [PATCH] tool/runruby.rb: test with smallest possible machine stack

I think I am using openssl-1.0.1s.
`HAVE_RB_FD_INIT` is not defined, but in fact AIX has `fd_mask`. It turned out that when defining `HAVE_RB_FD_INIT` by checking `fd_mask`, configure.in does not include sys/select.h. On AIX you have ... ReiOdaira (Rei Odaira)

08:40 PM Ruby Feature #13637: [PATCH] tool/runruby.rb: test with smallest possible machine stack

Thanks for the patch. Unfortunately, it did not solve the problem. Looks like this test does not call `nogvl_copy_stream_read_write()` but instead calls `copy_stream_fallback_body()`. As far as I read the code, there is no large array ... ReiOdaira (Rei Odaira)
