Issue #17289 has been updated by jeremyevans0 (Jeremy Evans). Status changed from Assigned to Feedback @joker1007 Can you reproduce this issue with Ruby 3.2 or the master branch? Can you reproduce this issue without the strptime gem? ---------------------------------------- Bug #17289: Time#strftime occurs Segmentation Fault on ruby-2.7.2p137 https://bugs.ruby-lang.org/issues/17289#change-104288 * Author: joker1007 (Tomohiro Hashidate) * Status: Feedback * Priority: Normal * Assignee: shyouhei (Shyouhei Urabe) * ruby -v: ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-linux] * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: REQUIRED ---------------------------------------- Segmentation Fault occurred when I run Time#strftime via Time#iso8601 on ruby-2.7.2. It occurs repeatedly about once a day in our system. Because it was not possible to make a reproduction case in a simple environment, I share the C Level backtrace and the control frame information at the time of occurrence. Also, I used strptime gem (https://github.com/nurse/strptime) to create the Time object.
