malloc(): unsorted double linked list corrupted
This is a copy&paste and not a normal crash report.
I was trying to match it against [1].
There are a few around samba_dnsupdate, but none matches the signature of yours.
Never the less without a full core dump and a reliable way to reproduce it is unlikely that a lot will happen (see the others on [1]
If you could report the crash [2] it would become part of this database where same crashes are mapped together. If there are spikes of the same kind it indicates that there might be a higher chance to trigger/debug it.
