確実に再現できるスクリプトができず、的が絞りきれない状態です。
ただ、
soap/wsdlDriver/test_calc.rb
を含めたテストだと落ちやすいようです。
テストの数を省いていくと、落ちる場所が、テストが終わって所要時間を表示する
  lib/test/unit/ui/console/testrunner.rb:81: [BUG] Segmentation fault
のところになってしまいました。

以下のようにしてバックトレースを取りました。
numeric.c の flo_to_sの
sprintf(buf, "%#.15g", value); 
で落ちてます。
私には、さっぱりわからないのですが、これで何かわかりますか？
