Subject: [PATCH] libtraceevent: Free "->" token in process_entry()
Date: Wed, 23 Jun 2021 22:47:30 -0400	[thread overview]
Message-ID: <20210623224730.6af93f6c@rorschach.local.home> (raw)

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

Fixing an issue with parsing "(REC)->" when it expected "REC->", changed
the test of "->" to read into a "token" variable instead of just
"expecting" it. This was needed to test for the ")" case. But since it is
now read into a token, that token needs to be freed. But that was missed.

Free the token.

This was found by the libtracefs "make test_mem" tests.

Fixes: 62823da1 ("libtraceevent: Handle parsing of "(REC)->" case")
