Subject: [PATCH 64/66] Fix latent bug in set_is_exec_point_at
Date: Mon, 24 Jun 2019 18:49:00 -0000 [thread overview]
Message-ID: <20190624184841.3492-15-tom@tromey.com> (raw)
In-Reply-To: <20190624184841.3492-1-tom@tromey.com>
valgrind pointed out that the TUI was using uninitialized memory in
set_is_exec_point_at. The bug is a missing check against LOA_ADDRESS,
causing gdb to examine the uninitialized bits of the "addr" field.
2019-06-23 Tom Tromey <tom@tromey.com>
* tui/tui-winsource.c
(tui_source_window_base::set_is_exec_point_at): Add check against
LOA_ADDRESS.
