[ruby-core:90880] [Ruby trunk Bug#15490] socket.rb - recurring segmentation faults

Issue #15490 has been updated by matthew.oriordan (Matthew O'Riordan).


Is there something I can do to help with the source of si_destination_compare, and the problem you believe is related to libsystem_info.dylib?

Bug #15490: socket.rb - recurring segmentation faults
https://bugs.ruby-lang.org/issues/15490#change-76066

* Author: matthew.oriordan (Matthew O'Riordan)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.6.0p0 (2018-12-25 revision 66547) [x86_64-darwin18]
* Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN
----------------------------------------
With Ruby 2.5.3p105 and now with Ruby 2.6.0 following our recent upgrade, we are sadly still seeing reasonably frequent segmentation faults from Ruby, specifically within socket.rb

Looking in socket.rb, it seems it's related to the address lookup:

    Addrinfo.getaddrinfo(nodename, service, family, socktype, protocol, flags).each(&block)

Segfault report below in full.  Attached are diagnostic reports too.  If there is anything I can do to help reproduce I will, however sadly I have never been able to reproduce reliably, yet sadly it happens once every few days.
