That's consistent with my experience through ubuntu 9.04. Also, the 
ubuntu-packaged ruby (which is 1.8.7) doesn't have the problem in 9.10.

It appears to be a gcc version issue. With 4.4.1, floats break; with 
4.3.4, all is ok.

Maybe this is related to the date parsing issue with 4.4.1 (when 
building the syntax gem).

It sounds like gcc 4.4.2 fixes some "serious bugs" in 4.4.1 [1], but the 
ubuntu packagers are reluctant to upgrade.[2] Fortunately, gcc-4.3 is 
easy to apt-get.
