Ruby 1.8.6 pl398 has been released. This release includes fixes for  
both win32 builds (thanks Luis!) and fixes a bug with extensions on  
Snow Leopard (thanks James!), as well as several other important  
backports and bug fixes, including a fix for IO#select that would  
cause it to sometimes return incorrect results when there multiple  
calls in progress on different threads.

It is available from [ruby-lang.org](http://ruby-lang.org) in the following locations:

Austin Z. reported last night that he was seeing an off-by-10  
error with floating point numbers, but I believe that the problem he  
reported is the same as was reported here:  
[http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/26937](http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/26937)

GCC 4.4.1 has some serious bugs, and that is what Ubuntu 9.04 ships  
with. Use apt-get to upgrade, and the problem should go away.

If it does not, or anyone encounters any other unexpected issues,  
please feel free to contact me.

Don’t thank me yet. Your preview worked for me, but this final version  
does not. ☹

Here’s the error:

Clarification: apt-get upgrade won’t help, because 4.4.1 is still the  
leading version in the ubuntu karmic (9.10) repositories, even if you  
include backports. The alternative is:

apt-get install gcc-4.3

And then set CC=“gcc-4.3” (or use update-alternatives).

Oh, now, that is curious. That’s on Snow Leopard? Those errors are  
arising from a backport of a threading patch. Let’s figure this out  
and get a pl399 out that fixes it. I’ll get in touch with you outside  
of the ML shortly.
