Hi,
I am having problems with lftp's filename completion. When I press <TAB>,
the program segfaults in a somewhat predictable manner. Does anyone have
the same problem? If there are more people with this problem, should I
file a bug report against lftp? I think it should at least have severity
'important', so I first want to be sure that this is a real bug.
I am using lftp 0.14.3.980328-1
This is the output from 'ldd /usr/bin/lftp':
libreadline.so.2 => /lib/libreadline.so.2 (0x40010000)
libncurses.so.3.4 => /lib/libncurses.so.3.4 (0x4003b000)
libresolv.so.2 => /lib/libresolv.so.2 (0x40080000)
libnsl.so.1 => /lib/libnsl.so.1 (0x4008e000)
libc.so.6 => /lib/libc.so.6 (0x40094000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
These libraries come from these packages:
libreadlineg2 2.1-8
ncurses3.4 1.9.9g-8
libc6 2.0.7pre1-4
Below are some transcripts to illustrate what I mean ("<TAB>" means I
pressed the TAB key):

What happens is this:
1. In the first case, there is nothing that starts with the letter 'a'. I
press <TAB> twice and get a segfault.
2. In the second case, there is one thing that starts with a 'p' and it
gets completed normally. In /pub, there are two things that start with
'wi', win3 and win95. I type 'wi', press <TAB>, it becomes 'win', I type
'9' and press <TAB> again and then I get the segfault.
3. In this case, I type 'p<TAB>li<TAB>d<TAB>b<TAB>' and then get the
segfault. In /pub/linux there are two things that start with 'd', 'debian'
and 'devel'. So, when I have '/pub/linux/de', I type 'b<TAB>' and then get
a segfault.
4. Now I am using another command. I type 'ls p<TAB>' and get the
segfault, even though there is exactly one thing that starts with 'p'.
5. This seems the same as 4., only this time I am in aother directory.
This puzzles me.
