From: dkennedy@... Date: 2014-07-23T14:45:19+00:00 Subject: [ruby-core:63980] [ruby-trunk - Bug #10045] SegFault in BigDecimal in 2.1.2p95 Issue #10045 has been updated by David Kennedy. I've been unable to replicate the segfault on demand. Because I've been unable to create the segfault on demand I am unwilling to remove the BigDecimal-1.2.5 gem - we started using it specifically to avoid another segfault a few months ago (possibly https://bugs.ruby-lang.org/issues/9657? but I am not sure) Looking at 2.1.2 head the integrated version of BigDecimal is at 2.1.4, so removing the BigDecimal external gem would leave us exposed to the previous segfault bug. ---------------------------------------- Bug #10045: SegFault in BigDecimal in 2.1.2p95 https://bugs.ruby-lang.org/issues/10045#change-47999 * Author: David Kennedy * Status: Open * Priority: High * Assignee: Kenta Murata * Category: core * Target version: next minor * ruby -v: ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-linux] * Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN ---------------------------------------- We use Travis CI to build our code and are having issues with some builds terminating; today we caught a segfault in one of the unresponsive builds' logs. It appears to be a segfault in `BigDecimal`. This is in Ruby `2.1.2p95` which is currently the latest version, and we cannot see a similar bug listed already. Unfortunately it is not easy to reproduce this bug on demand; it may be platform specific? Stack trace attached along with a little of the header matter from Travis to list Ruby versions *etc*. ~~~ setup build cache attempting to download cache archive found cache rvm.1 $ rvm use 2.1.2 --install --binary --fuzzy ruby-2.1.2 is not installed - installing.
