From 7763838e991e4d17a24c4214db5144eefd515543 Mon Sep 17 00:00:00 2001 From: Cupertino Miranda Date: Fri, 26 Aug 2016 22:15:23 +0200 Subject: [PATCH] Fixed issue with NULL pointer access on header var. Variable "header" in function is set conditionally, but was accessed without verifying if pointer was NULL. opcodes/ChangeLog: Cupertino Miranda * opcodes/arc-dis.c (print_insn_arc): Changed. --- opcodes/ChangeLog | 4 ++++ opcodes/arc-dis.c | 5 ++++- 2 files changed, 8 insertions(+), 1 deletion(-) diff --git a/opcodes/ChangeLog b/opcodes/ChangeLog index 9e41bc54882..fdb78afec13 100644 --- a/opcodes/ChangeLog +++ b/opcodes/ChangeLog @@ -1,3 +1,7 @@ +2016-08-30 Cupertino Miranda + + * opcodes/arc-dis.c (print_insn_arc): Changed. + 2016-08-26 Jose E.
