Subject: bug#28181: 26.0.50; emacs master segfaults on make-network-process, embedded device nokia n900
Date: Tue, 22 Aug 2017 01:00:28 +0000	[thread overview]
Message-ID: <cuo4lt05scz.fsf@chulpaca> (raw)


The problem is with emacs master.

"emacs -Q" and M-x eww "f1aldia.com" segfaults emacs.

the segfault happens on make-network-process (process.c) 

The same works fine on emacs-25.2 on the same device
