unbound-1.19.0 alloc_reg_obtain() core dumps

Hello,
I am working for Cloudflare where we seem to have a problem with
unbound-1.19.0. Estimated time in between crashes is around 450 days on a
single server. Cloudflare has lots of servers, and reasonable queries going
through systems, which means we see these crashes frequently enough that
this is a real problem.
By quickly looking the backtraces it looks like allocator is receiving a
null pointer and failing to follow ->next via that pointer. Something
somewhere earlier must have gone a bit wrong the pointer to be what it is.
This is where better expertise would be helpful.
To assist debug here are some backtrace samples. They do not have
absolutely all frames, but hopefully enough context to figure out how to
move forward with debugging if not even fix the issue.
Some what interestingly the second to last frame is on line
services/mesh.c:568 in three first samples but daemon/worker.c:2395 in last
one. I wonder if this a concurrency bug.
