(thanks for the workaround phasis68). Does this occur with gcc 4.8 anyone know? (i.e. was it a bug in 4.7 now fixed in 4.8...?) ---------------------------------------- Bug #6383: Segfault in Timeout module when compiled with GCC 4.7 https://bugs.ruby-lang.org/issues/6383#change-39933 Author: budu (Nicolas Buduroi) Status: Open Priority: High Assignee: Category: Target version: Ruby 1.8.7 ruby -v: ruby 1.8.7 (2012-02-08 patchlevel 358) [i686-linux] As described in a post (https://bbs.archlinux.org/viewtopic.php?id=139547) on the ArchLinux forum, there's an issue with Ruby 1.8.7 when compiled with GCC 4.7 on a modern Linux system. Ruby segfault as soon as we try to install a gem, although it seems to work fine for trivial things. Here's an output of the error message: /opt/ruby1.8/lib/ruby/1.8/timeout.rb:60: [BUG] Segmentation fault ruby 1.8.7 (2012-02-08 patchlevel 358) [i686-linux] It can be circumvented by installing older versions of GCC but this is a very time consuming operation and it's not possible one every systems. -- http://bugs.ruby-lang.org/
