Subject: bug#42160: Issue with Man-kill and background process.
Date: Thu, 2 Jul 2020 04:23:09 +0200	[thread overview]
Message-ID: <20200702022309.bpj4t77e73n23c4y@ergus> (raw)
In-Reply-To: 20200702022309.bpj4t77e73n23c4y.ref@ergus

When using man with big manuals (like gcc). There is an error when
trying to quit with k just after opening the manual.
This seems to be related with the formating process that is running in
the background.

To reproduce the issue:

emacs -Q
M-x toggle-debug-on-error RET
M-x man RET
gcc RET
k

And I get this error message:

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  Man-bgproc-filter(#<process man> "nt, there is no need to use address spaces like \"_...")
