#3507: Mutt ignores SIGWINCH when built with --enable-imap
--------------------+-------------------------------------------------------
Reporter: vinc17 | Owner: mutt-dev
Type: defect | Status: new
Priority: minor | Milestone:
Component: mutt | Version:
Keywords: |
--------------------+-------------------------------------------------------
When I configure Mutt with "./configure --enable-imap", it ignores
SIGWINCH under some occasions (see below how to reproduce the bug). No
such problem when I just do "./configure". It seems that this problem is
recent.
1. Open a 80x40 xterm.[[BR]]
2. Run screen in it.[[BR]]
3. Run "mutt -F /dev/null".[[BR]]
4. Detach the session.[[BR]]
5. Open a 80x60 xterm.[[BR]]
6. Reattach the session with "screen -r".
Result: There are 20 blank lines above the help line.
According to strace, Mutt received a SIGWINCH as expected, but it has
apparently been ignored.

This can also sometimes be reproduced when increasing the xterm window
(height or width).
