crashes. Non-incremental updates and received just fine.

Console output from the sending (12.1) side:

Receiving side dmesg:

pid 1128 (zfs), jid 0, uid 0: exited on signal 6 (core dumped)
pid 1127 (sudo), jid 0, uid 0: exited on signal 6

I have zfs.core, but not sure what tool to use to get the backtrace from it:
/usr/libexec/gdb complains on it with the following:

[...]
Error while reading shared library symbols:
Dwarf Error: wrong version in compilation unit header (is 4, should be 2) [in
module /usr/lib/debug/lib/libjail.so.1.debug]
[...and so on ...]
