Well, it's reasonably stable, but it crashes with an assertion about make_lisp_buffer_stream_1 where the start is greater than the end, just like my earlier reports with 2.95.2 So perhaps this isn't just a compiler bug. There might be more to it. With Sun C, I haven't run into this yet, but I don't compile with optimization on because I can't debug it then. :-( Ray
