From: nobu@... Date: 2018-12-31T08:51:15+00:00 Subject: [ruby-core:90835] [Ruby trunk Bug#15490] socket.rb - recurring segmentation faults Issue #15490 has been updated by nobu (Nobuyoshi Nakada). File bug-15490.log added Description updated Always it happens here, though I couldn't find the source of `si_destination_compare`, it may be a problem in libsystem_info.dylib. ``` 7 ??? 0x00007fc6cddeaac0 0 + 140491834174144 8 libsystem_trace.dylib 0x00007fff6e31adb4 os_log_type_enabled + 627 9 libsystem_info.dylib 0x00007fff6e23305b si_destination_compare_statistics + 1659 10 libsystem_info.dylib 0x00007fff6e231bf3 si_destination_compare_internal + 707 11 libsystem_info.dylib 0x00007fff6e231762 si_destination_compare + 530 12 libsystem_info.dylib 0x00007fff6e20f95f _gai_addr_sort + 111 13 libsystem_c.dylib 0x00007fff6e1b9a0f _isort + 193 14 libsystem_c.dylib 0x00007fff6e1b993c _qsort + 2159 15 libsystem_info.dylib 0x00007fff6e207135 _gai_sort_list + 789 16 libsystem_info.dylib 0x00007fff6e205b88 si_addrinfo + 2040 17 libsystem_info.dylib 0x00007fff6e205262 _getaddrinfo_internal + 242 18 libsystem_info.dylib 0x00007fff6e20515d getaddrinfo + 61 ``` ---------------------------------------- Bug #15490: socket.rb - recurring segmentation faults https://bugs.ruby-lang.org/issues/15490#change-76018 * 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. ---Files-------------------------------- ruby_2018-12-31-032126-2_MacBook-Pro.crash (46.8 KB) ruby_2018-12-31-032126-3_MacBook-Pro.crash (46.8 KB) ruby_2018-12-31-032126-1_MacBook-Pro.crash (46.8 KB) ruby_2018-12-31-032125_MacBook-Pro.crash (46.8 KB) bug-15490.log (833 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
