Please show the Lisp backtrace for this.  All I see here is that Emacs
called the debugger, so there was some Lisp error it tried to report.
I also see that inside the debugger, Emacs deleted some subprocess for
some reason, which triggered redisplay (as expected), which hit an
assertion violation due to some inconsistency in the buffer text.
That's about all I can glean from this.
