Solaris 10 (SPARC) と
ruby 1.8.6 (2007-09-24 patchlevel 111) [sparc-solaris2.10]
ruby 1.8.6 (2008-02-05 patchlevel 5000) [sparc-solaris2.10]
でも再現しました。

スタックトレースをとってみましたが、これでわかりますか?

$ gzip -d <ruby-1.8.6-p111.tar.gz |tar xf -
$ cd ruby-1.8.6-p111
$ ./configure && make
...
$ env -i RUBYLIB=lib:.ext/sparc-solaris2.10 ./ruby /path/to/test.rb
./lib/timeout.rb:52: [BUG] Segmentation fault
ruby 1.8.6 (2007-09-24) [sparc-solaris2.10]
