From: "jeremyevans0 (Jeremy Evans)" Date: 2021-10-05T14:43:13+00:00 Subject: [ruby-core:105560] [Ruby master Bug#18240] Random segfault on a local Rails server Issue #18240 has been updated by jeremyevans0 (Jeremy Evans). Unfortunately, I don't think there is enough information provided to help diagnose the specific cause of the issue (the general cause is likely to be memory corruption). The following 3rd party C-extensions are in use: ``` nio4r bindex byebug stackprof bcrypt panko_serializer oj ffi puma pg nokogiri bootsnap msgpack ``` A memory issue in any of those could cause a segfault in `append_features`. If it is possible to disable the use of all or most of the external C extensions and see if that makes that problem go away, that would be one way to go about diagnosing the problem. ---------------------------------------- Bug #18240: Random segfault on a local Rails server https://bugs.ruby-lang.org/issues/18240#change-94015 * Author: Benoit_Tigeot (Benoit Tigeot) * Status: Open * Priority: Normal * ruby -v: 3.0.2 * Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN ---------------------------------------- Hello I am having random segfault locally when rails a basic rails app. The control frame is weird: | -- Control frame information ----------------------------------------------- web | c:0073 p:---- s:0470 e:000469 CFUNC :append_features web | c:0072 p:---- s:0467 e:000466 CFUNC :include ---Files-------------------------------- Untitled.txt (724 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
