Subject: [PATCH] strbuf: use valid pointer in strbuf_remove()
Date: Tue, 13 Sep 2016 18:40:22 +0200 [thread overview]
Message-ID: <408af1a3-6867-2ff5-c97f-3eb884412ad8@web.de> (raw)
The fourth argument of strbuf_splice() is passed to memcpy(3), which is
not supposed to handle NULL pointers. Let's be extra careful and use a
valid empty string instead. It even shortens the source code. :)
