stable/7 zdb(1M) Assertion failed.

[jhell]

I keep getting the following when trying to use any options with zdb(1M)

One for example,

# zdb -dd pool/local
Assertion failed: (´2), function rwlp->rw_count == 0, file 
/usr/src/cddl/lib/libzpool/../../../cddl/contrib/opensolaris/lib/libzpool/common/kernel.c, 
line 195.

Anyone know what might be causing this ?.

On the other hand if I do not use any options and just provide the pool it 
works happily, but with that alone it does not give me the information 
that I was looking for.

If more information is needed let me know.

Thanks,
