についてのお話にて やまだは言いました…

あ> Debian m68k(sid)で1.6.3がbuildできないようです.

make testの中でも, 先程とは違う場所で, segvをくらうようです.

extmk.rbのときにはsegvをくらうタイミングがまちまちなのですが
make testの場合だと同じ場所でくらいます. 
sample/test.rbの952行目です. 

  $ LD_PRELOAD=./libruby.so ./ruby sample/test.rb 
  sample/test.rb:952: [BUG] Segmentation fault
  ruby 1.6.3 (2001-03-28) [m68k-linux]
