From 93422725a0a8248d97b67cdbc20e065f5164e089 Mon Sep 17 00:00:00 2001 From: "Richard W.M. Jones" Date: Thu, 6 Feb 2020 10:27:48 +0000 Subject: [PATCH] cat: Fix GCC 10 warning. I believe this warning is bogus, but simply initializing the local variable is enough to avoid it. log.c: In function 'do_log': log.c:390:7: error: 'comm_len' may be used uninitialized in this function [-Werror=maybe-uninitialized] 390 | printf (" %.*s", (int) comm_len, comm); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (cherry picked from commit 4e199494c41d3240aa5c0708887b7a7513c6b6f2) --- cat/log.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/cat/log.c b/cat/log.c index 25107e25f..f8a5c85f2 100644 --- a/cat/log.c +++ b/cat/log.c @@ -337,7 +337,7 @@ do_log_journal (void) while ((r = guestfs_journal_next (g)) > 0) { CLEANUP_FREE_XATTR_LIST struct guestfs_xattr_list *xattrs = NULL; const char *priority_str, *identifier, *comm, *pid, *message; - size_t priority_len, identifier_len, comm_len, pid_len, message_len; + size_t priority_len, identifier_len, comm_len = 0, pid_len, message_len; int priority = LOG_INFO; int64_t ts; -- 2.18.4
