FreeBSD 10.3: core dump on zfs destroy

[Shiva Bhanujan]

Hello,

On a FreeBSD 10.3 system, I'm getting a core dump on zfs destroy.

[root at FreeBSD_10_3 ~]#
[root at FreeBSD_10_3 ~]# zfs create zroot/fs
[root at FreeBSD_10_3 ~]#
[root at FreeBSD_10_3 ~]# zfs destroy zroot/fs
Assertion failed: (avl_find() succeeded inside avl_add()), file /usr/src/cddl/lib/libuutil/../../../sys/cddl/contrib/opensolaris/common/avl/avl.c, line 649.

I believe this is the same issue that was reported in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=196533.  The backtrace using gdb does look the same.  I've tried the same on different pools on the same server, but I keep seeing the same error.

I can send the core file, if requested.    Can somebody give some insights into what this might be?

Regards,
Shiva
