logger(1) exited on signal 11 after r326525 -> r326622

I noticed among the messages on the console during the final stages of
the transition from single- to multi-user mode:

I don't see any similar issues on my (headless) build machine; I
just checked further, and verified that booting head _at_r326622 is the
only time I see them.  (The laptop spends most of its time running
stable/11.)  And the laptop didn't whine when booting head _at_r326525.

I'm trying to extract useful information from /logger.core, but not
doing so well on the "useful" part of that -- e.g.:

g1-252(12.0-C)[10] sudo lldb -c logger.core 
Password:
(lldb) target create --core "logger.core"
Core file '/logger.core' (x86_64) was loaded.
(lldb) bt
* thread #1, name = 'logger', stop reason = signal SIGSEGV
  * frame #0: 0x0000000000402152
    frame #1: 0x0000000800603618
(lldb) 


Actually writing to the log (obviously!) works....

As far as I can tell, the laptop is otherwise functioning normally.
Strange....

Peace,
david
