I just installed snv_34 and was unable to reproduce the problem you
described. Is it possible there''s something screwy going on with the
files in /usr/lib/dtrace? Please try running with DTRACE_DEBUG set in
your environment and attach the output -- maybe that can give us some
clue as to what''s going on.

Adam Leventhal,???

	Thanks for your response.
    I have knowned this problem''s root cause.This is not a
dtrace''s bug, just because I replaced some system files like
/kernel/genunix with version mismatch.

I just hit a similar error while doing some unrelated testing.
I had my test system booted with an Install kernel tarball
(or it may have just had a new unix slapped on).

It looks as if the ctf data may have become confused. Perhaps
something thought the tag associated with cl_name was
associated with a different structure than struct sclass?

When I booted back to the BFUed image DTrace was happy
again.
