From cb14c4a535ca95bb87d47be284f447c9325733fd Mon Sep 17 00:00:00 2001 From: Yusuke Endoh Date: Sat, 12 Oct 2019 21:10:49 +0900 Subject: missing/setproctitle.c: remove nonsense NULL check If fmt is NULL, ptitle is uninitialized and used. SETPROCTITLE(3bsd) says "If fmt is NULL, the process title is restored", but looks like the feature is not implemented in missing/setproctitle.c. At least the source code of ruby does not pass NULL to the function. So I assume this function requires non-NULL fmt.
