The XCode kit version reported by autotools is 10.13 (just like mine) but apart from that I can't find any other build details, nor confirm that it is macOS 10.12 indeed. Can somebody point me to the build config (trying to find out if it's using LODE or otherwise) and the system details for that tinderbox?

I cannot reproduce your failure with various (though all 
--enable-dbgutil) master builds on macOS High Sierra (10.13.1).  They 
successfully build 'make check screenshot'.

However, I have routinely seen sporadic test failures during 'make 
check' with stack traces resembling yours in the past.  Those completely 
stopped to happen for me a while ago.  I had assumed it was related to 
jmux' VCL scheduler changes back then.  But it could probably instead 
have been related to my switch from macOS 10.12 to 10.13, which I did at 
about the same time IIRC.
