[ruby-core:81797] [Ruby trunk Bug#13155] Segfault testing Pry

Issue #13155 has been updated by wanabe (_ wanabe).


I guess it is the same issue as #13605 because of the log pattern.
(using pry, T_NONE, newobj_slowpath_wb_protected and gc_mark_children)

Bug #13155: Segfault testing Pry

* 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
