It seems that we hit following error [1]. The patch is available at [2]. Unfortunately it was not merged into 1.8.7 :/ [1] https://bugs.gentoo.org/234877?id=234877 [2] http://redmine.ruby-lang.org/projects/ruby-19/repository/revisions/20587 I did some tests and I think there is some strange bug in ranging with floats. i:i386|m:i686 bah@hp-xw4200-01 [smoke-test]# ruby -e 'a = (1.0...6.4).step(1.8).to_a; p a; p a.size' [1.0, 2.8, 4.6, 6.4] <--- FAIL 4 i:i386|m:i686 bah@hp-xw4200-01 [smoke-test]# ruby -e 'a = (1...6).step(1).to_a; p a; p a.size' [1, 2, 3, 4, 5] 5 i:i386|m:i686 bah@hp-xw4200-01 [smoke-test]# ruby -e 'a = (1.0...6.4).step(1).to_a; p a; p a.size' [1.0, 2.0, 3.0, 4.0, 5.0, 6.0] 6 i:i386|m:i686 bah@hp-xw4200-01 [smoke-test]# ruby -e 'a = (1.0...7.0).step(1).to_a; p a; p a.size' [1.0, 2.0, 3.0, 4.0, 5.0, 6.0] 6 i:i386|m:i686 bah@hp-xw4200-01 [smoke-test]# ruby -e 'a = (1.0...7.1).step(1).to_a; p a; p a.size' [1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0] 7 i:i386|m:i686 bah@hp-xw4200-01 [smoke-test]# ruby -e 'a = (1.0...13.6).step(1.8).to_a; p a; p a.size' [1.0, 2.8, 4.6, 6.4, 8.2, 10.0, 11.8] 7 i:i386|m:i686 bah@hp-xw4200-01 [smoke-test]# ruby -e 'a = (1.0...13.6).step(1.2).to_a; p a; p a.size' [1.0, 2.2, 3.4, 4.6, 5.8, 7.0, 8.2, 9.4, 10.6, 11.8, 13.0] 11 i:i386|m:i686 bah@hp-xw4200-01 [smoke-test]# ruby -e 'a = (1.0...4.6).step(1.2).to_a; p a; p a.size' [1.0, 2.2, 3.4] 3 i:i386|m:i686 bah@hp-xw4200-01 [smoke-test]# ruby -e 'a = (1.0...9.4).step(1.2).to_a; p a; p a.size' [1.0, 2.2, 3.4, 4.6, 5.8, 7.0, 8.2, 9.4] <--- FAIL 8 i:i386|m:i686 bah@hp-xw4200-01 [smoke-test]# ruby -e 'a = (1...8).step(1).to_a; p a; p a.size' [1, 2, 3, 4, 5, 6, 7] 7 i:i386|m:i686 bah@hp-xw4200-01 [smoke-test]# ruby -e 'a = (1...4).step(1).to_a; p a; p a.size' [1, 2, 3] 3 ^ ruby-1.8.7.352-3 Well, it seems this issue happens only on i386. i:ppc64|m:ppc64 root@ibm-js12-02 [~]# ruby -e 'a = (1.0...6.4).step(1.8).to_a; p a; p a.size' [1.0, 2.8, 4.6] 3 i:ppc64|m:ppc64 root@ibm-js12-02 [~]# ruby -e 'a = (1.0...9.4).step(1.2).to_a; p a; p a.size' [1.0, 2.2, 3.4, 4.6, 5.8, 7.0, 8.2] 7 i:ppc64|m:ppc64 root@ibm-js12-02 [~]# ruby -e 'a = (1...4).step(1).to_a; p a; p a.size' [1, 2, 3] 3 i:ppc64|m:ppc64 root@ibm-js12-02 [~]# ruby -e 'a = (1...8).step(1).to_a; p a; p a.size' [1, 2, 3, 4, 5, 6, 7] 7 New bug about range issue: https://bugzilla.redhat.com/show_bug.cgi?id=733372 It seems to be platform specific issue. I have tried to write reproducer in C with the same (wrong) result. The -ffloat-store might fix the issue, however the performance impact is unclear. Similar complain was risen in Ruby Redmine [1] but the patch [2] is not worth of any action, since it fixes the consequences, no the reasons.
