I've upgraded glibc to version 2.14.1-r2 and changed LC_MESSAGES;). New backtrace: gdb /usr/bin/lftp GNU gdb (Gentoo 7.3.1 p2) 7.3.1 Copyright (C) 2011 Free Software Foundation, Inc.

Same in 4.3.3, probably as well in older versions...
Could you take this upstream? I thought I was still subscribed but I don't seem to get the mail any longer.
Also, I guess this is a minor problem as it's easy to prevent.
Created attachment 299361 [details, diff] empty local cmd fix Patch from upstream. Works for me.
Thanks.
It still behaves funny (note the change in the prompt) but at least it keeps running properly: jer@wieneke /tmp/portage/net-ftp/lftp-4.3.4/work/lftp-4.3.4 $ ./src/lftp lftp :~> local Usage: local cmd [args...] lftp :~> local '' Ambiguous command `'. lftp localhost:/tmp/portage/net-ftp/lftp-4.3.4/work/lftp-4.3.4> [_]
Fixed in 3.4.3-r1.
This is only cosmetic problem;) Thanks.
