Subject: output: Fix segfault for writing output outside a command invocation.
X-Git-Tag: v0.7.3~19
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1388653736c11bce0f3b2be983065730bc895cc3;p=pspp-builds.git

output: Fix segfault for writing output outside a command invocation.

Running "make check" made this problem obvious, but it hadn't shown up in
my in-GUI testing.
