----------------------------------------
Bug #14403: Crash and coredump (Stack consistency error) on ruby 2.5.0
https://bugs.ruby-lang.org/issues/14403

* Author: jrochkind (jonathan rochkind)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-darwin16]
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
This reproduction script seems to make no sense, because it's extracted from an actual program where I encountered this bug, and trimmed down to be the minimal I can get to reproduce. 

Parts of the script that seem irrelevant (like the `if` check that should never be true), if removed, remove the reproduction. This is why I'm glad I'm not a C programmer! 

This executes without core dump on `ruby 2.4.3p205 (2017-12-14 revision 61247) [x86_64-darwin16]` -- runs fine, does not reproduce error, on 2.4. 

I believe on ruby 2.5 it also reproduces on travis (which is where I originally encountered the problem), so I don't believe it is unique to the MacOS ruby build I am reporting here.
