Bug #14402

Crash and coredump (Stack consistency error) on ruby 2.5.0

Added by jrochkind (jonathan rochkind) about 3 years ago. Updated about 3 years ago.

Target version:
ruby -v:
ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-darwin16]


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.
