Subject: [PATCH 03/16] perf annotate: Fix sizeof_sym_hist overflow issue
Date: Mon, 5 Oct 2015 18:03:25 -0300 [thread overview]
Message-ID: <1444079018-31421-4-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1444079018-31421-1-git-send-email-acme@kernel.org>
From: Jiri Olsa <jolsa@kernel.org>
The annotated_source::sizeof_sym_hist could easily overflow int size,
resulting in crash in __symbol__inc_addr_samples.
Changing its type int size_t as was probably intended from beginning
based on the initialization code in symbol__alloc_hist.
