I've just tried the test case with Mono from SVN. It doesn't segfault, but
throws an NullReferenceException. The stacktrace is a very long list consisting
of the same invocation over and over again:

..
  at System.Text.RegularExpressions.Interpreter.Eval (Mode mode, System.Int32&
ref_ptr, Int32 pc) [0x00000] 
  at System.Text.RegularExpressions.Interpreter.Eval (Mode mode, System.Int32&
ref_ptr, Int32 pc) [0x00000] 
  at System.Text.RegularExpressions.Interpreter.Eval (Mode mode, System.Int32&
ref_ptr, Int32 pc) [0x00000] 
..

So the bug is still there and easily reproducible.
