bug#14559: 24.3.50; accept-process-output hang

[Chep]

accept-process-output hangs sometimes. It always happens with erc (decrypting
password file with gpg), sometimes with ampc and ispell.

create a ~/.authinfo.gpg encrypted file (I think you can write what you want in
this file)
 
start emacs -Q
M-x toggle-debug-on-quit
M-x erc
RET RET RET (default values)
*emacs hangs after displaying "Decrypting /home/chep/.authinfo.gpg...done" *
C-g

(I'm going through old bug reports that have unfortunately gotten no
responses yet.)

This sounds to me like the epg command doesn't output the expected data.

Are you still seeing this problem in more modern versions of Emacs?

I don't even remember this bug. I use erc everyday with authinfo encrypted file
on emacs 27.0.50 without any problem.
