Subject: [PATCH 19/20] Use SCOPE_EXIT in write_gcore_file
Date: Wed, 13 Feb 2019 21:53:00 -0000	[thread overview]
Message-ID: <20190213212927.9474-20-tom@tromey.com> (raw)
In-Reply-To: <20190213212927.9474-1-tom@tromey.com>

This replaces a try/catch in write_gcore_file with a use of SCOPE_EXIT
instead.  I find that this is simpler to understand.

	* gcore.c (write_gcore_file): Use SCOPE_EXIT.
