I don't remember.  I have encountered this error multiple times before and
given up debugging something.  Since one generally runs into bugs when
doing work
(that is not hacking on Emacs itself), it's helpful to be able to debug with
minimal obstruction, otherwise it becomes an unjustifiable distraction
from the main task.

I'll try to get a master build working again, but it's always a balance between
instability, getting new bugfixes, and getting actual work done (which
unfortunately
doesn't include hacking on Emacs for me).
