05-Jul-2012 12:31 AM Wataru Kimura: Summary: On 10.8 Developer Preview, Bignum class of Ruby (/usr/bin/ruby) seems to be broken. Steps to Reproduce: Terminal.app $ svn co http://svn.ruby-lang.org/repos/ruby/tags/v1_8_7_358 $ cd v1_8_7_358 $ ln -s /usr/bin/ruby ./miniruby $ /usr/bin/ruby sample/test.rb | grep not $ /usr/bin/ruby test/ruby/test_bignum.rb Expected Results: pass all tests. $ /usr/bin/ruby sample/test.rb | grep not $ /usr/bin/ruby test/ruby/test_bignum.rb Loaded suite test/ruby/test_bignum Started ..... Finished in 0.00527 seconds. 5 tests, 172 assertions, 0 failures, 0 errors Actual Results: failure some tests of Bignum. $ /usr/bin/ruby sample/test.rb | grep not not ok bignum 5 -- sample/test.rb:1279 not ok bignum 7 -- sample/test.rb:1281 not ok bignum 8 -- sample/test.rb:1282 not ok bignum 9 -- sample/test.rb:1284 not ok bignum 12 -- sample/test.rb:1292 $ /usr/bin/ruby test/ruby/test_bignum.rb- Loaded suite test/ruby/test_bignum Started F....

I tested ruby-1.8.7 with clang and some configure options. only ruby built with CFLAGS="-O0 -std=c89" works fine. optimization of llvm/clang will break ruby-1.8. 10-Jul-2012 11:48 PM Wataru Kimura: I wrote a patch against "numeric.c". this patch solves errors written in this report.
