The above backtrace seems to tell the following story:
. Emacs loaded some package
. loading the package triggered its processing (including loading of
some other package)
. eventually, as part of processing the loaded packages, Emacs
called 'intern' (frame #74), which called check_obarray, which
signaled a wrong-type-argument error (frame #71)
. the error handling called the Lisp debugger
. the debugger caused redisplay, which called cairo_show_glyphs,
which caused an X error (frame #19)
. the X error caused the X connection to close
. Emacs then tried to shut down in an orderly fashion, which again
triggered redisplay, which aborted (most probably because
X-related data structures are invalid, due to the closed X
connection)
I suspect that the error we tried to signal in frame #71 has something
to do with the recent changes in obarray handling, with which the
package that is being loaded here does not comply. So I added Mattias
to the discussion.
I also see that we detect recursive invocations of redisplay too late,
so I have now fixed that on master.
As for the cause of this -- some problem in ftcrfont_draw -- maybe Po
Lu can suggest some ideas. I guess we should try to understand what
kind of X error was caused here?
