Issue #13637 has been updated by ReiOdaira (Rei Odaira).


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 to explicitly include it to have `fd_mask`.  I fixed it in r59440, and the SystemStackError disappeared.  

Thanks much for your help!

Feature #13637: [PATCH] tool/runruby.rb: test with smallest possible machine stack
https://bugs.ruby-lang.org/issues/13637#change-65971

* Author: normalperson (Eric Wong)
* Status: Closed
* Priority: Normal
* Assignee: 
* Target version: 
----------------------------------------
Lets ensure none of our C functions use too much stack space and
fix all excessive stack usage before releasing the next version.
Reducing C stack usage should reduce conservative GC scanning
time and improve performance.

Hopefully there are no objections; I will commit in a few days.

If there are platform-dependent CI failures; excessive stack
usage should be fixed; rather than increasing minimum values or
removing these envs from testing.
