Hello ;)
Tested OpenZFSOnWindows-debug-20200814.exe version today
Creature:
zpool create -O dedup=on -O casesensitivity=insensitive -O atime=off -o ashift=12 dedu PHYSICALDRIVE4

Sorry for the delay.

 ZFSin!dmu_objset_pool [C:\src\ZFSin\ZFSin\zfs\module\zfs\dmu_objset.c @ 112] 
 ZFSin!zfs_get_done+0x46 [C:\src\ZFSin\ZFSin\zfs\module\zfs\zfs_vnops.c @ 1219] 
Attempt to read from address ffffffffffffffff

1219 VN_RELE_ASYNC(ZTOV(zp), dsl_pool_vnrele_taskq(dmu_objset_pool(os)));

Interesting- not seen this one before. Presumably in this "done" function, the "os" or "ds" has been released already.

Perhaps I am not sending enough data to detect the problem? What other data can I collect?
I tested the version of OpenZFSOnWindows-debug-20200825.exe
Pool creation,
zpool create -O compress=lz4 -O dedup=on -O casesensitivity=insensitive -O atime=off -o ashift=12 dedu PHYSICALDRIVE"?"
working conditions are the same.
And again bsod, SYSTEM_SERVICE_EXCEPTION (3b)

Thanks for the feedback - I'm knee deep in the new port so we can merge ZFSin with upstream, but I'll get back to this.
