Subject: [PATCH 2/9] perf annotate: Reuse path from the result of addr2line
Date: Thu,  1 Aug 2013 11:55:37 +0900	[thread overview]
Message-ID: <1375325744-26613-3-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1375325744-26613-1-git-send-email-namhyung@kernel.org>

From: Namhyung Kim <namhyung.kim@lge.com>

In the symbol__get_source_line(), path and src_line->path will have
same value, but they were allocated separately, and leaks one.
Just share path to src_line->path.
