Bug#292397: vim freezes on swap file prompt
Hi! As far as I know, this bug was fixed in one of the final rc releases of vim7. Shouldn't it be closed?

Hi!
I've done some more debugging on this problem, and it seems only a few
of the vim variants are affected. Specifically, I can reprocude the
problem using vim.gnome, vim.python and vim.perl, but vim.basic,
vim.gtk, vim.tiny, vim.lesstif, vim.ruby, vi.tcl and vim.full work fine.
Also, I've build a version of vim.perl with -ggdb3, and can reproduce
the problem there. GDB gives the following backtrace after the freeze:

If I set a breakpoint on line 3026 of misc1.c (just after the
ui_inchar() call), I can verify that indeed a special key code is
returned (i.e. the cursor I pressed). Specifically, the key code
returned is 0x80 0x8a 0x95 (\eku, which I guess means the uparrow).
However, this key is not handled at all: in the FEAT_MBYTE ifdef on
line 3084, the continue is called, and the loop progresses to the next
iteration, after which the key is never returned anymore by
get_keystroke().
So, the problem seems to be that the special sequences that are
generated by the cursor keys are mistaken for an incomplete multibyte
sequence; the check for such a special sequence is only done in
do_diaglog(), after get_keystroke() has returned.
The following patch solves this, and works fine here. Please include it
in the debian packages and also send it upstream.

Bug#292397: vim freezes on swap file prompt
Package: vim
Version: 1:6.3-058+1
Severity: important
When I start vim to edit a file that is already being edited, vim
nicely shows me the swap file already exists prompt. If I press any
normal (alphanumeric) key here, everything keeps working fine.
However, if I press a cursor key on this screen, vim simple freezes
and refuses to reacted to anything (including ^Z and ^C) except an
external TERM signal.
My cursor keys return the usual \e[A, \e[B, \e[C, \e[D escape
sequences.
The problem seems locale-dependent. if I start vim with
[EMAIL PROTECTED]/tmp env -i LC_ALL=C vim test
it works fine. If I set LC_ALL to en_US.UTF8 or nl_NL.UTF8 instead of
C, the bug returns. With en_US or en_US.ISO-8859-15, the bug doesn't
occur either. I've tries this using varying terminals (xterm, aterm,
console).
An strace of the frozen process shows
| select(1, [0], NULL, [0], {0, 10}) = 0 (Timeout)
| ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost -isig -icanon -echo
...}) = 0
| select(1, [0], NULL, [0], {0, 10}) = 0 (Timeout)

| ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost -isig -icanon -echo
...}) = 0
etc. When I press a key, it says:
| select(1, [0], NULL, [0], {0, 10}) = 0 (Timeout)
| ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost -isig -icanon -echo
...}) = 0
| select(1, [0], NULL, [0], {0, 10}) = 1 (in [0], left {0, 17000})
| select(1, [0], NULL, [0], NULL) = 1 (in [0])

| ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost -isig -icanon -echo
...}) = 0
(which shows vim does actually receives the key I typed)
after which it returns to the select/ioctl loop.
