I didn't trigger the error on purpose but by accident. A package used
obarray wrong (with nil instead of 0) which caused an error like this:
(wrong-type-argument obarrayp [nil nil nil nil nil nil nil nil nil nil
nil nil nil])
The error did not immediately cause a crash but some time after.
I have a gdb attached, If get a crash now I can send these outputs.
I'm not sure if this related but sometimes Emacs is stuck rendering
org-mode buffers till it receives SIGUSR2 or user input.
Requests such as emacsclient -nc don't reach Emacs until either of the
two above happens.
