malloc(): unsorted double linked list corrupted
Aborted
This appears to be a very difficult bug to reproduce. It only appeared
once and with the second invocation succeeding without issue.
Fortunately apport managed to preserve the core dump. After unpacking
it with apport-unpack and loading the core dump with gdb, the full
stack trace is as follows:

It is apparent that a lot of information has been optimized out by the
compiler. But based on the signatures in #8 and #9, I'm guessing this
may have something to do with saving the state file.
I am using Ubuntu Eoan (19.10) on amd64 with kernel 5.3.0-24-lowlatency
#26-Ubuntu and libc6 2.30-0ubuntu2.
Yours truly,
