[ruby-core:81747] [Ruby trunk Bug#13155] Segfault testing Pry

From: v.ondruch@...
Date: 2017-06-23 08:48:21 UTC
List: ruby-core #81747
Issue #13155 has been updated by vo.x (Vit Ondruch).

File segv3 added
File segv4 added
ruby -v changed from ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux] to ruby 2.4.1p111 (2017-03-22 revision 58053) [powerpc64le-linux]

This was triggered again during automatic rebuild of Fedora's Pry package

https://apps.fedoraproject.org/koschei/build/2977931

and it also failed in my subsequent build. See the attached logs. So 2.4.1 is still affected :/

* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
Trying to fix Pry on Fedora Rawhide, I get random segfaults. Unfortunately, I can't see any pattern in them. The backtrace is always different. Attaching two logs in case it might make the issue more obvious. Here are some package versions which might be of interest:

$ rpm -q readline
readline-7.0-4.fc26.x86_64

$ rpm -q glibc
glibc-2.24.90-28.fc26.x86_64
