[ruby-core:70688] [Ruby trunk - Bug #11514] AIX6.1 - Ruby 2.2.3 - Segmentation fault in :byteslice

Issue #11514 has been updated by Tony Reix.


I had attached all the details in a file. However, I have an "internal error" when trying to look at the file.
I haven't put all details in defect because, in some other projects, we are required to not put all details at first, only a summary.
Here are all the details:

Testing Ruby 2.2.3 on AIX6.1 built with xlc (same with gcc) leads to a reproducible crash.
